Jin-Yi Yu: Okay commodity party so homework. Number two is still today. And after 1pm today.
Jin-Yi Yu: The homeowner history will be released on canvas preschool that
Jin-Yi Yu: One welcome home or number three which they will match Thursday.
Jin-Yi Yu: And the meantime I'm sinking to do it.
Jin-Yi Yu: So this is week number
Jin-Yi Yu: Or if we don't come the first day in the first week. So this is a possibility, week four, and next week's in looks fine. And I'm thinking to to
Jin-Yi Yu: Meet turn on November 12
Jin-Yi Yu: And it will be a title have the immediate term corporate VC, we talk about from first full stature or or it fully autonomous very consecration.
Jin-Yi Yu: Which I haven't even talked about yet. So hopefully next week, I will be able to finish the discussion of the general general saturation atmosphere can then
Jin-Yi Yu: Then we ought to the
Jin-Yi Yu: Meter nano member tell which is a service tech our send you an email to confirm this, so just remind you, the homework. Number three is released this afternoon. Okay, so let me share the screen right now.
Jin-Yi Yu: So today we are going to go to the
Jin-Yi Yu: The
Jin-Yi Yu: The radiation transfer part of the discussion. So basically, so far we already talked about global energy parents and from that group or entity parents point of view will realize that we need to discuss the greenhouse effect.
Jin-Yi Yu: And then in this chapter. Right now radiation transfer is trying to explain why we have this greenhouse effect. So I believe most of you already have.
Jin-Yi Yu: Some basic idea or some really idea related to the chat, and we'll talk about today. So today, actually, there's only streaky show we want to
Jin-Yi Yu: Discuss first is that the radiation coming from sun solar radiation and the radiation that out pregnant Planet Earth really out the true story. The issue they are coming at a different frequency that's the
Jin-Yi Yu: Key information. Want to learn from this chapter.
Jin-Yi Yu: Welcome. This
Jin-Yi Yu: And the second concept we wanted to learn and this is
Jin-Yi Yu: Face to explain why.
Jin-Yi Yu: The radiation comes to solar radiation. Radiation has dominated by different frequency Ben and it is because of these people frequency pen.
Jin-Yi Yu: The greenhouse effect can be produced. So greenhouse gases greenhouse effect can be produced is based on them most important reason is solar radiation and Theresa radiation.
Jin-Yi Yu: operate at a different frequency. And that's why we are going house effect. And the second part of this lecture, try to explain why we have such kind of different dominance in frequency for different radiation. And then finally we're going to quickly explaining that
Jin-Yi Yu: The three or four major action green a to radiation transferring our commercial customers receive, we have to learn from this chapter. So this chapter is relatively short
Jin-Yi Yu: And then also I mentioned read a bit about how this car Federal Aviation but it's what are these radiated conducted curriculum is right. So what is this particular term. This is just a knowledge. Okay, now let me call so
Jin-Yi Yu: The first part of this chapter.
Jin-Yi Yu: But why the solar radiation turret territory creation operate at a different for radiation pen or frequency
Jin-Yi Yu: So before that we'll talk about are important or radiation and virtually all the exchange of energy between us and the rest of the universe takes place by radiation because radiation transfer of energy.
Jin-Yi Yu: Does not require mass to get involved. So you can operate in a vacuum space. But you say our climate system when we have
Jin-Yi Yu: Water air then we can also transfer the exchange of energy by the other two form, which is a convection and
Jin-Yi Yu: Conduction
Jin-Yi Yu: Radiation transfer is also a major energy transfer between must fear and the underlying surface that we're going to talk about this briefly next chapter, when we talk about surface.
Jin-Yi Yu: And it
Jin-Yi Yu: Parents and this concept is more relatable hai na na GE
Jin-Yi Yu: Or you study and insulate or air pollution near to the boundary of our customers fear.
Jin-Yi Yu: So we are not going to pay a lot of tension and this one in the next chapter. So next chapter is a very short chapter
Jin-Yi Yu: Okay. Now let us go to radiation score. First, this is the equities, right, because the textbook experience comes up and we can be sometimes very scary go look at it textbooks showing all awesome mathematic equation. So here I put this slide here, just try to
Jin-Yi Yu: Put your exercise. How you handle automatic in this textbook, even though we don't care about peace detail formula, they stealing from you want to make this measure yourself can handle and can read all these mathematical
Jin-Yi Yu: Formula. And then the other thing is try to get yourself familiar familiar with some of this.
Jin-Yi Yu: Terminology related to radiation and here the terminology we want to talk about is the radium intensity
Jin-Yi Yu: And radiant intensity is the energy, could you only time like unit area per unit frequency interval per unit sorry ankle that
Jin-Yi Yu: Among the radiation we receive that's Korean intensity. Okay. This is important for a long to
Jin-Yi Yu: Explain this formula. So here you can see that based on
Jin-Yi Yu: Based on the
Jin-Yi Yu: Definition
Jin-Yi Yu: This radiation intensity is per square area.
Jin-Yi Yu: And that's per, per unit time per sorry and goddesses sorry ankle, the top you and per
Jin-Yi Yu: Year per area PR
Jin-Yi Yu: The PR frequency. So you can see that it is related to
Jin-Yi Yu: This sorry NGO
Jin-Yi Yu: Sorry ankle means less quirkiness, where a sudden I comes in. Right. So you already mentioned last time.
Jin-Yi Yu: What is the ankle disquiet the direction Sunday comes in in that direction coast, who are had this ankle is covert. Anybody remember
Kyle Manley: Gina
Jin-Yi Yu: Yes, that's what we call dizziness.
Jin-Yi Yu: Ankle right
Jin-Yi Yu: Because Ian's ankle tell us that how much, how was the NGO that that's the radiation come into your square area we want the radiation computers penetrated
Jin-Yi Yu: Perpendicular as as much as possible. So we want our DNS and go to be close to zero, then you covered strongest radiation.
Jin-Yi Yu: In serious angle is 90 degree means the southern the southern radiation sunlight coming from horizon for happened during the sunrise and sunset and then we can see that is
Jin-Yi Yu: This Culpeper sorry ankle and then that's one and then curved surface area you're standing here and you have a surface area of PA right
Jin-Yi Yu: And then you use this service area to receive radiation. So radiating even coming from the founders ankle, but it can be the same angle crash there 40 degree here.
Jin-Yi Yu: And then you can because you can move around 360 degree right here standing here and then he will, in the same 40 degree. This seals can rotate it maintained body degree and then just rotate it around you at a 360 degree. And so your service area is actually relate to this ankle not
Jin-Yi Yu: You're going around and this ankle Sukkot around by 360 degree. That's right, go from zero to 6062 and Saudi angle that is the rational sunlight coming to your service.
Jin-Yi Yu: And the angle between a direction and your overhead is the sorry ankle and one is this one.
Jin-Yi Yu: Let's go this way, which go from zero to 90 degree because can go from
Jin-Yi Yu: Particular zero or 90 degree. And then this radiation can come in depends on. This is a show where it is you know where it is, you
Jin-Yi Yu: Or which frequency. And that's why disciple. Sorry. Ankle beside the unit area, we need to also consider where does the radiation come from coming into our area so low status. This forcing neither conceited right what angle that
Jin-Yi Yu: Radiation comes in from which direction from you east from us, or from yourself or from your nose or. Also, is it from the visible light frequency or infrared or from different different
Jin-Yi Yu: Frequencies.
Jin-Yi Yu: And then so
Jin-Yi Yu: When we define it so ready intensity started this disquiet how strong the lows radiation coming relate to commit a political ankle committed a particular direction coming from a particular frequency
Jin-Yi Yu: But we are not going to work on this. Right. So for this class, we only want to consider all radiation from 360 degrees around you fuzziness angles zero to 90 degree and integrate together and
Jin-Yi Yu: It and we only want to care. How does radiation comes in at any particular frequency. Right. So this is the code or radiation will receive
Jin-Yi Yu: But radiation comes in from different frequency. But that's what this is actual want to emphasize. So in order to just worry about a frequency. And that's why we take this
Jin-Yi Yu: Radiation here.
Jin-Yi Yu: And we integrate over 360 degree here in a way for us and go zero to Nina. Nina snuggled 90 they would get this phone. Okay, so I usually show the slightest because the textbook.
Jin-Yi Yu: The squad is one. I just don't want you to get scared. So, and we only talk about radiation comes in related to
Jin-Yi Yu: Any particular frequency pan, then the physical physics or it basically is already tell us that the radiation intensity at any particular frequency parent is related to the frequency called got radiation. Right. So the frequency
Jin-Yi Yu: Is equal to one, one over with productions. So they have to carry the same information.
Jin-Yi Yu: So the physical or pillars that we are more radiation carried by any particular frequency radiation is controlled by this formula, a constant times is frequency and these frequencies one over wavelength. So that means when you have higher frequency you have
Jin-Yi Yu: Higher frequency you have shorter way when you have lower frequency you have longer way. So based on this formula we realize that the shorter way.
Jin-Yi Yu: Man, instead of the higher the frequency, then the stronger the radiation energy can be carried by that particular frequency pen.
Jin-Yi Yu: So this is a very important concept means that when we talk about radiation. When you come to Showtime shorter wavelengths or radiation.
Jin-Yi Yu: Like an X rays, gamma ray, they tend to carry very, very strong energy only come to longer and longer with that stuff Inveraray
Jin-Yi Yu: Michael way written radio away. They kept longer know whoever else then they carry weaker and weaker Amanda radiated energy that's a key.
Jin-Yi Yu: Information sort of radiation emitted by earth which is an infrared, which is considered relatively long
Jin-Yi Yu: Not so are we call tourists cholesterol radiation. Don't wave radiation and they tend to be we're not internal but the amount of radiation.
Jin-Yi Yu: In the solar radiation is happening in the visa per line and they tend to be shorter. Those are certainly
Jin-Yi Yu: So we usually call solar radiation soap week in the terrestrial radiation from us long with in sort of radiation can to have a stronger radiation intensity, then the
Jin-Yi Yu: Peripheral radiation. Okay, as a concept we want to be on. So now all the discussion in the first two. So I try to bring you to a concert
Jin-Yi Yu: When we can see the radiation, we have to ask which frequency of of the radiation that we are talking about.
Jin-Yi Yu: Because chris chris radiation coming from many different frequency band. So we need to consider consider only after you allow radiation energy to come into the different frequencies. And then we can continue to have you.
Jin-Yi Yu: Sort of radiation coming at one part of frequency then Teresa radiation can our system from the
Jin-Yi Yu: Frequency of radiation and then a lot greenhouse effect to happen. Okay, or this discussion is try to lead to a statement. So here, based on that must medics formula we recognize we need to consider different radiation at a different
Jin-Yi Yu: Wavelengths right so we need to divide the radiation into different way for them to spend right and then those this table. Our last
Jin-Yi Yu: Wait for the spender we define and wish you remember so from very, very see from the very, very sharp
Jin-Yi Yu: Very sharp weybridge in a 10 to the minus
Jin-Yi Yu: six millimeter. So it's 10
Jin-Yi Yu: Minus six Michael meter.
Jin-Yi Yu: Then we have this camera and sort of what is the, what hope is this size key. So to visualize this size, the size the party atomic the size are coming
Jin-Yi Yu: New careers and then we come to read a bit longer than camp x ray and even longer to come to ultraviolet radiation and kind of be polite but laws are still consider shop with anything come all the way complete polar loss, I consider a short
Jin-Yi Yu: Wave vent for climate consideration and then we come to the capital bit longer wavelength like infrared or Michael at this number one, we have one to 100 Michael meter in dense that so hopefully this does this, there's a spot a size of a task. Then we come to a little bit longer wavelength.
Jin-Yi Yu: And then we continue come to
Jin-Yi Yu: Next one will come to radio way and then everything as in this also Michael So it's from shot.
Jin-Yi Yu: We're friends.
Jin-Yi Yu: Too long where parents can. What is the Enron center chop.
Jin-Yi Yu: No question. Let me see, what is your question.
Jerry Lin: Asking one does radiation can a nosy
Jin-Yi Yu: Could you say that again.
Jerry Lin: When does radiation, because I know using like a which
Jin-Yi Yu: Should be radiation become Iron Man's
Jin-Yi Yu: Best the different concepts on the same report. Okay, nice means that you break a pattern between the director and the optimal for military industrial in April, the energy level and energy level in order to be strong enough to do the airlines is has rely on comma ray
Jerry Lin: X ray
Jin-Yi Yu: And so that these two frequency pennies operate at a typical minus six to potential minus eight to 10 to the minus six.
Jin-Yi Yu: Micron. So only these two frequency of radiation is strong enough to cost on nice of the modern era monitor
Jin-Yi Yu: It. So now this size. Let's try to explain what is the major frequency. So I want you to be able to get ideas in a homework question asked you to rank order.
Jin-Yi Yu: You the wavelengths are the frequency of last different radiation pen see Michael is here. Michael is longer, the inquiry right you've raised
Jin-Yi Yu: Is in somewhere around the lens of our post radiation operate in a Michael way is has even longer wavelength radio is even longer and radio is on the size of finger or the way to the size of the mantle. OK, so now
Jin-Yi Yu: After this, this concept then we realize that whenever solar radiation sunlight.
Jin-Yi Yu: Hope when urs produce radiation why Simon us produce radiation, because any party where he has a non zero Kelvin degree temperature issue produce radiation had a total of mama sigma teeth. What a powerful. So this is the total amount
Jin-Yi Yu: Of re the Asian
Jin-Yi Yu: Send out by any property based on his temperature, what is total amount means because when any property backers see
Jin-Yi Yu: He produced radiation from where from zero my home to one my country, my country, my coffee. So try
Jin-Yi Yu: The zero point something might come here. Your point here is the baseball i and then all over the 10 my phone is infrared and then come to radio microwave radio waves. So in the same thing for some for new
Jin-Yi Yu: agey you also produced from extreme calm very visible in very all the way to to radio way. Right. So no matter which party particular area, including you and me, we produce radiation.
Jin-Yi Yu: A the frequency that we mentioned and that all these frequency energy or frequency pen and altogether. Is this total energy. Mmm.
Jin-Yi Yu: So the reason I mentioned is is that even though we only talk about previous or you're only talking about a total amount of radiation.
Jin-Yi Yu: Energy produced by any black party is based on his formula. However, you have to recognize that no matter which product body produce radiation. You put irrigation all frequency
Jin-Yi Yu: Okay, so all object radio energy not merely at one single weapons, but over wider range of different wavelengths. You say the the uterus say be shot no solar radiation is dominated by beats for like a shorter wavelengths. And that's what we call a shortwave radio. Yes.
Jin-Yi Yu: Is the event or most of his energy
Jin-Yi Yu: Concentrate neon this shuttle web reds baseball right ultraviolet radiation karma extract is still produced at radiation at Inveraray makeover.
Jin-Yi Yu: But it overflows frequency in be a mammal. The intensity radiation produced by setting up my son came to be weaker compared to radiation center by Sun at
Jin-Yi Yu: X x ray Cameron visible. Right. That's why we simplified solar radiation us Shockwave creation. Same thing sensing radiation produced by earth also can coming up. I'm extremely also come with
Jin-Yi Yu: Come from extra camera or a visible right behind where most of the strongest strongest radiation intensity occur near the infrared area. That's how we simplified to describe
Jin-Yi Yu: Teresa radiation as a longer radiation. That's the key concept into the river here. So all after. Yes, Chris.
Melisa Perut: They also mean by them being able to change their wavelength that they can emit zero radiation, too. So it's also in the spectrum.
Melisa Perut: So let's say is, so let's say, as you said, if he had zero Calvin and as your temperature, then you won't admit any regulation.
Melisa Perut: So, and, but if you heat up or if you cool down, you would start to emit radiation. So that can also change.
Jin-Yi Yu: Right. Yes. Yeah. For example, if
Jin-Yi Yu: Somehow we hit up
Jin-Yi Yu: By 20 time our temperature to become close to the sun, then are terrorists radiation will move from dominant radiation to become short, we're here.
Jin-Yi Yu: So the only thing that determine which frequency pin in that property is going to eat meat. Most of his energy is only also controlled by temperature. Yeah. So let me go to black quickly.
Jin-Yi Yu: So the sun radium also more more energy than Earth. This is due to sigma, it will force, but a greatest intensity of solar radiation is
Jin-Yi Yu: Radiant and whether it's much shorter than that of equated energy emitted by the earth and this concern.
Jin-Yi Yu: Is described by the other fiscal. It's called within sort of so you know radiation. When we talk about Tula Stephen Bozeman not tell you that the total amount energy
Jin-Yi Yu: No matter which which frequency when you add it all together. The total amount is only controlled by the power for of your property temperature and the wisdom also further tell you that
Jin-Yi Yu: Stephen was not counting the total amount, but this total amount can be took IDs or equal. Look, I
Jin-Yi Yu: Miss right, it has concentrate his greatest intensity ever shorter wavelength for longer websites which are your whole more uncool is based on this.
Jin-Yi Yu: We install we install carrion tell you that a maximum radiation. The weapons that you put the property produce the maximum the greatest creation is
Jin-Yi Yu: Where bluejeans is inversely proportional to temperature right so we install reader to an object object objective maxima and meet with friends or radiation to the objects temperature
Jin-Yi Yu: So the web lens of the maximum immediate remediation plan object is inversely proportional to the objects absolute temperature in Kelvin quicker.
Jin-Yi Yu: So this is the winds, nor is very important to explain why we have greenhouse effect because based on this. We just thought we know that suns temperature is 6000 degree. Okay. And then you use that wins wins lot of evidence produced by the
Jin-Yi Yu: Solar some not solar radiation maximum must be has a strongest intensity at this particular frequency which is close to 0.5 micron meter and this is exactly
Jin-Yi Yu: Let's go back to look at this table.
Jin-Yi Yu: Queries 0.5 0.5 micron is to a brand is Related lists for that task for most awesome I comes in in a bespoke like frequency
Jin-Yi Yu: And then page on the same fit with. Now we can find out it would put in Earth's temperature from 300 degrees right is 50 degrees C plus 273 equal to Calvin is to
Jin-Yi Yu: At Calvin said cross the country then you find out that be how Teresa radiation will have this greatest intensity around 10 micron. Okay. And Tim Tim my micro meter.
Jin-Yi Yu: Is let's look at our team is here is weapons for my computer code 100 millimeter, we can, which is really good for right then.
Jin-Yi Yu: So those are the two number you should remember. Anytime we talk about what is the radius solar radiation.
Jin-Yi Yu: Major weapons. You have to say visa for about 0.5 millimeter. Now, what is the major radiation pen back out. Teresa retention personalization center.
Jin-Yi Yu: Radiation a quote on our climate. This happened about 10 millimeter infrared. Okay, so it is you so far. Just try to add about this concept that means now based on
Jin-Yi Yu: The comes up, how
Jin-Yi Yu: Stephen Boltzmann know
Jin-Yi Yu: Which is a maximum total amount of energy, set up a private party is to the power for his temperature and based on Winslow, you also tell us that this radiation he his condo have the strongest intensity Mia. This particular web lines.
Jin-Yi Yu: From the maximum, which is predate one over temperature, but it has come merge these two concepts to the speaker so not as described solar radiation.
Jin-Yi Yu: Plastic disquiet terrestrial radiation. Right. And then we try to draw these to radiation in
Jin-Yi Yu: In the cause of function of frequency. So we are going to do that.
Jin-Yi Yu: I said, now we're frequency. This is frequency process has to wavelengths
Jin-Yi Yu: Of the radiation. So whether it's one zero and then why my home to my home to my home or the 10 my home meter either been on 400
Jin-Yi Yu: So if we want to draw solar radiation does take Ricardo, how are you going to join your jaw at these, and he's going to concentrate on 0.5 millimeter. So it's going to be maxima.
Jin-Yi Yu: Here.
Jin-Yi Yu: Sort of Asian you happy to address peek at your point five and it decrease or to the artificiality but this is our solar radiation. Now that store the radiation for the
Jin-Yi Yu: Paris radiation how I'm going to talk. So, of course, he has to be added 10 Michael meter. So he should concentrate near can Michael meter.
Jin-Yi Yu: And I'm a big supporter camaraderie. They are very small and also very smart even longer weapons. Okay, if I look at my party, the zero Corona does this satisfy Stephen Boltzmann or and Winslow on
Jin-Yi Yu: First, does this satisfy the withdrawal.
Jin-Yi Yu: From the maximum equal to something the Pi, Pi
Jin-Yi Yu: Divided by that the temperature of that happen.
Jin-Yi Yu: To I throw in the correct way to be consistent pattern Winslow, yes. Right, because
Jin-Yi Yu: Teresa radiation temperature is very low.
Jin-Yi Yu: So t small, so the Mexico. Mexico Web. The Web Lindsay produce maximum radio here. This is small.
Jin-Yi Yu: And these are must be wrong. So don't wait can I come and solar radiation son has a very high temperature here. And then, so this is high IQ number and then so the maximum add produce must happen at a small bird right here. Now, does it satisfy the Stephen Postman or not anybody is
Jin-Yi Yu: No. Yeah, why not.
Juan Tolento: In the same height on the Y axis.
Jin-Yi Yu: Exactly.
Juan Tolento: Intensity, yes.
Jin-Yi Yu: Because the amount of energy.
Jin-Yi Yu: But showing up in this product which meaning that the, the surface area my area under the curve.
Jin-Yi Yu: On my almost the same, but a Stephen Boltzmann not tell us that it makes the total energy that area underneath to curb has to be proportional to the power for your temperature and solid him some signs temperature is so small. So correctly issue to solar radiation in this way. Very nice.
Jin-Yi Yu: So,
Jin-Yi Yu: Actually this is still not correct. So really correct way to refresh we install and Stephen postman, or is this
Jin-Yi Yu: If this is a solar radiation right concentrate maximum energy
Jin-Yi Yu: Based upon 0.5 millimeter and when we saw the police radiation is only here.
Jin-Yi Yu: You can even see the PR 000000000 to 10 my coin pick up a little bit and then go into, you're not gonna even see
Jin-Yi Yu: The crystal radiation. When you come, put it together. Was that a solar radiation. That's why the speaker into zoom into this small crew and show you that actually concentrate right so this one is the best reflect me the Stephen possible or not prosper, which is not good. So now everything
Jin-Yi Yu: Has a sofa. Yes, please.
Juan Tolento: Add a question, going back to that graph.
Juan Tolento: Yes, um,
Juan Tolento: So normally when I look at a body graph, it usually looks like this, or one side is like much more slower than the other. And I guess for me, it would just make a lot more sense. It feels like a symmetric Gaussian. So why, why isn't it.
Jin-Yi Yu: That's a good question. Yeah. I don't know why and how to answer that question and browsing, if you want to call us in the news also will be symmetric, right, but pricing impossible to produce and cultural shift because you shape is a black star ratings are symmetric
Jin-Yi Yu: To
Jin-Yi Yu: Your central point because coaching is express
Jin-Yi Yu: Something that x minus x zero square divided by the way, but as a skill how x plus y minus y zero square because I know why. So everything
Jin-Yi Yu: To the east of x zero progress of X zero, or no, so y zero to a software has to be symmetric because take a square right x minus zero.
Jin-Yi Yu: Squared is Amanda x is bigger than x zero to composite the value of x is the modern MC or to become negative matter because you take a square foot because some so you don't have counseling, then this next no evidence has to be somewhere.
Jin-Yi Yu: In the middle of this spectrum, right. So since this solar radiation is buyers skilled howdy shorter wavelength. So this product has caught at least
Jin-Yi Yu: There's no way to get a very symmetric. So if we want to make a symmetric, then you need a break the precept of stem and that radiation from some
Jin-Yi Yu: The sun, sun image radiation airport wavelength is we want to do is symmetrical. Our puppies.
Jin-Yi Yu: To come down exactly like this, then that means to be 0000 radiation and all the other frequency, but then that is not going to satisfy the statement or object ready energy add or wavelengths right so that's why it is it has to be skilled, we cannot be symmetric. OK, so now come to
Jin-Yi Yu: The key part of our greenhouse effect Amy's in cocoa bar is physics and all these phases. Try to deliver this slide. This slide tell you that if you saw X coordinate us where brands or radiation comes in, of course, of
Jin-Yi Yu: Our me system, then we find out all the solar radiation comes in at
Jin-Yi Yu: one corner of this coordinate which is shorter wavelength.
Jin-Yi Yu: In all the tertiary the to get our current system protocol done accounting system all happen at this long.
Jin-Yi Yu: With lens of this x coordinate, right, and why that's because of Israel. So I want you, I want you to be able to say this to save people's why we have
Jin-Yi Yu: Greenhouse effect. And it's all us because sort of evasion comes in at the wavelengths that different
Jin-Yi Yu: Completely different from the personalization code and I can happen at the aeroplane, they don't come in the same where brands in our atmosphere only can absorb one particular frequency print so he must be absorbed sort of vacation. He cannot absorb
Jin-Yi Yu: Teresa radiation. He must be absorbed Teresa radiation. He cannot absorb solar radiation, because these two radiation come in and now it's a different frequency back
Jin-Yi Yu: In God's the most fundamental fact that developing give rise to our greenhouse effect. And then while the ratings. You want to come in and out a different frequency
Jin-Yi Yu: Answers because of wisdom. Right, so only be able to say that. So now this peek at exp explain why we have solar radiation, a greenhouse effect, as I say,
Jin-Yi Yu: Soda comes in from zero microbe to mostly concentrated on 0.5 micron meter which is visible right and then decrease it is so Theresa radiating try to
Jin-Yi Yu: Pull them are climbing produce radiation for muscle radiation concentrate at the 10 millimeter. And as far as come in and out at a different frequency pain and not allow those
Jin-Yi Yu: Now us atmosphere to produce different absorption property and then produce greenhouse effect because what is a greenhouse greenhouse, you have a process of
Jin-Yi Yu: Building and this class is building around some night to comes in, without being effective. So this roof. The classroom is our philosophy.
Jin-Yi Yu: In this classroom, even though we are now Samantha coming. However, when we have heat. Try to get out of this building because trapped in this heat get out of this building get trapped by the roof is our producer radiation that. So now let's come to
Jin-Yi Yu: This most important part of the first part of his lecture greenhouse effect. And now you see consolidation comes in. This is a frequency, but
Jin-Yi Yu: I'm s coordinate this area is zero, my comp here is hundreds party certain micrometres right so now you see summer comes in at his particular show a
Jin-Yi Yu: Caribbean region co op from our own way. Now, but it comes in head a long way in which the total amount radiation to come into this world right now so I keep your rainbow color from Kolkata one color income, you know, this is our chemistry.
Jin-Yi Yu: Right. In each case, nitrogen, oxygen, hot more also in carbon dioxide, water vapor
Jin-Yi Yu: Here the textbook give you this for
Jin-Yi Yu: A monster cases as example and then these will tell you lab. Each of these four cases. How much absorption making produced and any particular frequency, but from zero, Michael.
Jin-Yi Yu: Your point one to point two, all the way from show way too long way. Okay, now you can see that the absorption can go from zero percent. So that's the look at nitrogen took a here.
Jin-Yi Yu: Nothing, nothing, nothing 0000 only this blue area means that podcast can produce some absorption popular ideation at a particular frequency
Jin-Yi Yu: Because if our nitrogen is not true, not true. No point 000 almost nitrogen episode. Nothing about short way he absorbed nothing in the wrong way.
Jin-Yi Yu: With that weakness. He only to a little bit of absorption somewhere around three to six millimeter. Okay. But that's not a major
Jin-Yi Yu: Radiation comes in orientation call. So that's why because nitrogen is the most abundant case, you know, thermosphere see what he can do to solar radiation zero
Jin-Yi Yu: We can do to Teresa attention zero. That's why this most abundant guess is not important for our timing, because it doesn't interfere with radiation. Now let's look at a second apartment. Guess you know atmosphere oxygen right she asked you to around absorption near where anybody
Jin-Yi Yu: Your point to point to the very ratio evidence. What is the name of that radiation pen or
Wherever.
Jin-Yi Yu: Even earlier because this is
Jin-Yi Yu: As close to that also Vida in finance can be
Jin-Yi Yu: See this figure Taylor's all this power radiation is absorbed by us awesome oxygen molecule that we mentioned this time absorption by as such a monocle in the first week.
Jin-Yi Yu: When do we measure
Gamma
Jin-Yi Yu: Gamma ray, X ray. Yes. Perhaps the oxygen molecule episode camera extract. How many were
Jerry Lin: Transfer is associated know
thermosphere
Jin-Yi Yu: Yeah, so this one tell you to they have atmosphere, when it is always on all three.
Jin-Yi Yu: Absorb this
Jin-Yi Yu: Ultraviolet radiation pen. You happy stratosphere, when it is oxygen molecule or to absorb this extra karma rate your happiness thermosphere so this
Jin-Yi Yu: Picture telling you this is happening in our circle our
Jin-Yi Yu: middle to upper atmosphere, including stratosphere, mesosphere, but oxygen has do nothing. There's no almost no clue. When we come to this, for I almost no clue. Almost no almost no one wants to pursue radiation except this one. See, very interesting. So oxygen actually can black
Jin-Yi Yu: Most of our peripheral vision happening at a 10 millimeter, but inside this 10 millimeter area oxygen extra producer absorption pen.
Jin-Yi Yu: You need to be able to set this all up assumption pen absorption nine. Okay, that's where it up particular frequency pen or particular frequency
Jin-Yi Yu: Number with Call nine some of this gas is or produce absorption or radiation, but other than that is pretty much
Jin-Yi Yu: Zero absorption took a carbon dioxide is completed. No clue. No clue in this in the solar radiation range and every continue coco, coco in 30 Teresa RADIATION AREA. You see that
Jin-Yi Yu: A lot of poo poo poo poo. Right. So the carbon dioxide. He became the produced radiation when it comes to Teresa radiation Pessoa
Jin-Yi Yu: Carbon dioxide is a greenhouse gases, because he truck radiation at the frequency interval that how peripheral radiation a cook. Most of energy and SMC we look at the water vapor here 000000 may come to
Jin-Yi Yu: Near Infrared very conceited can have absorption absorption and then follow it. So that's why water vapor is a natural greenhouse gases, because we produce a lot of glue Miss Teresa radiation.
Jin-Yi Yu: Interval. OK. So now you'll notice that all is related to be one pen can 1.0 it doesn't go more at least, but is coda particular path. Okay, nice because water weapon.
Jin-Yi Yu: A carbon dioxide. They absorb radiation to change their energy level and all these are the most weekends their energy level is for example 136 two to 14
Jin-Yi Yu: And then two, three suck at it doesn't go from 161 6162 and so it is not continuously all this energy never read it on air molecules.
Jin-Yi Yu: Are restricted. So they only can only absorb particular energy, a man not fit exactly
Jin-Yi Yu: That it fits exactly a manga it jump from one energy level to the next energy level. That's what all these absorption happening particular frequency particular frequency. And then if you read a researcher, they were series of social pen.
Jin-Yi Yu: Right was copper oxide for water vapor a newer say this carbon dioxide, one of a rotation pen.
Jin-Yi Yu: Or vibration pen. Okay, so everything I want to say here is I just want you to
Jin-Yi Yu: Get an idea of what those community means which will mention about all this notation pen vibration is try to describe the energy level that allow this molecule to absorb radiation at a particular frequency. Okay, so don't be scared by all this terminology
Jin-Yi Yu: Professor, yes.
When
Kyle Manley: The incoming shortwave gets absorbed in the thermosphere does it just get readmitted back to space or just some of it get absorbed and remitted back into towards Earth.
Jin-Yi Yu: So you said me agree emitted by who
Kyle Manley: Well, it gets absorbed right by
Kyle Manley: Yet the oxygen ozone.
Jin-Yi Yu: Yes.
Kyle Manley: Go, then what happens
Jin-Yi Yu: When absorb it right, it's going to what does, what does taxis use that additional energy for for increasing the temperature of oxygen, right.
Jin-Yi Yu: Right all machinery, the atmospheric air in the thermosphere so the master in a similar spirit increase temperature after absorption of extra income everything you need to be emitted, but he couldn't agree emitted.
Jin-Yi Yu: long wavelength, because Adam, it is atmospheric air in a similar sphere which is going to do the emission and the atmosphere. Then we ask ourselves, what is the temperature of
Jin-Yi Yu: Atmospheric mess at the similar sphere, right. We know number is our temperature service costs 315 decreasing right who damn warm up and cool down to the maximum or it is for anybody.
Jin-Yi Yu: That's called missile costs. Right.
Jin-Yi Yu: So can be to cool down to tropopause increase in the stratosphere, including quote on quote unquote and put them all away the call the standard you know holder master is a purple mesosphere, which is called metal. Pause
Jin-Yi Yu: Right, and then committed, you have a woman well as customers via summer school can be woman as much as 130 Quincy
Jin-Yi Yu: Right. So when camara extra can absorb here in warm up temperature here in your country emitted. We can read it, it does not need to be emitted at exactly the same frequency parent comes in.
Jin-Yi Yu: This is your question. Yes.
Kyle Manley: Thank you.
Jin-Yi Yu: Because a frequency. I will read.
Jin-Yi Yu: Blue emitted radiation vector space and Pam Cody kamata must be depends on what temperature iraq time for his summer sphere and similar sphere is very warm so 150 degree. So I think this was
Jin-Yi Yu: Properly and asked him science temperature. Something about to solve them or something. So this is still
Jin-Yi Yu: Much summary. And actually, I believe. This one is still going to be somewhere in the near infrared a the most close to this color right here. So even though it must be a similar spirit absorb Comrie would agree in remediate it doesn't, not to be also remediated Cameron x ray
Jin-Yi Yu: Okay, now
Jin-Yi Yu: This is the site can see the most interesting in Boulder very, very informative and very important concept. Okay. So now after we handled the absorption by each individual
Jin-Yi Yu: Cases in a common sphere, then we add altogether because all the number was showing here going from zero to 100% and then we get a pen.
Jin-Yi Yu: So this is whole atmosphere by adding or cast together and see how such a more of 100% absorption. So in this frequency in the net.
Jin-Yi Yu: Effect of atmosphere associates close to 100% and near very low frequency part see carbon dioxide and water vapor almost all the radiation causes outsourcing is also not 100% hundred percent rule.
Jin-Yi Yu: Then in between.
Jin-Yi Yu: Over this before, right, we can see that our total absorption. In fact, by our chemistry is almost zero. So sunlight coming in. So our atmosphere.
Jin-Yi Yu: Sinking our must be completely transparent to sunlight, but a Teresa didn't try to go out from near infrared to
Jin-Yi Yu: Him very and and radio and see is almost completed through a all this territory they try to call our company the truck and only in this area between nine to eight to 10 millimeter our radiation from the surface. If we are here.
Jin-Yi Yu: This is person is we are standing here and it is a tree and the surface and we all produce radiation. Try to cannot telecare and you are astronaut
Jin-Yi Yu: He suspended you fold in yourself in this in this in this in the in the space you try to measure how much radiation coming out from service, then you find our most orientation at every frequency cap rate.
Jin-Yi Yu: But everything's come up on service Capra, bye bye bye atmosphere by crowd my water vapor. So these are soon I only see the radiation center better crowd.
Jin-Yi Yu: At a couple other must be off the air at a couple of them must be so the astronaut cannot see the service. It doesn't happen. Need a service, right.
Jin-Yi Yu: So that if you have an info Ricardo and you're stronger you look come two hours each other. See what happened and the other service, you will not be able to see because most or
Jin-Yi Yu: Radiation produce fires happen. It is frequency pen and all these frequency prep Capra, but if you want to design your cargo to metric. Allow yourself to see
Jin-Yi Yu: What happened, and the earth service, not just on the top of the bottom as we want to see what happened is that a service that ocean temperature
Jin-Yi Yu: And tree grows and how many building increasing, decreasing on the other side of it. You have to allow all these
Jin-Yi Yu: Earth's temperature particular occasion you have allowed him to escape so performance without being can absorb it, then you can have dessert is this cargo even Ricardo
Jin-Yi Yu: Then which frequency of the radiation, you're going to use. Look at this, you're going to miss your, your cargo is designed to receive radiation coming up around a tool can Michael meter because
Jin-Yi Yu: If they if any service object, you mean tree or ocean produce temperature therapy radiation.
Jin-Yi Yu: Even know all the other frequency radiation emitted by You. Me and ocean cup product for all there's a portion of every day at eight to 10 millimeter
Jin-Yi Yu: Is going to call so it must be. We are being in the field will not be in the field. I mean, they're pre revenue and come into your car.
Jin-Yi Yu: And you can convert the intensity of this radiation eight to 10 millimeter into to guess what is the temperature of this radiation, because all the
Jin-Yi Yu: radiation intensity is related power for temperature in this particular frequency paint you see Pacific Ocean in Mayberry restaurant reviews. It means a rock kind of season.
Jin-Yi Yu: Priscilla, she must be very, very well. Right. Any other season you wear a scarf or the candle to put to us, you measure the radiation.
Jin-Yi Yu: Eight to 10 Macromedia coming up on press TV doing a particular scene is very, very we then Stephen Postman Postman or tell you that the ocean temperature era particular season must be very little to allow you to see. So our chemistry. Okay, and that's why this is called
Jin-Yi Yu: A chemistry window. This is the radiation pen that if you are working in NASA has engineer when you design your soccer, you want to design center that can detect radiation happening in this particular frequency pen because they can escape soda chemistry that's quite recall
Jin-Yi Yu: But I must break a window. Okay, so now
Jerry Lin: That's all. Yes.
Jin-Yi Yu: Gary
Jerry Lin: Do you know why the scale or the wavelength is variable.
Jin-Yi Yu: We are going to say in a second.
Jerry Lin: part now.
Jin-Yi Yu: We're going to, we're going to explain why.
Jin-Yi Yu: This radiation.
Jin-Yi Yu: To eat meat or can absorb it why covered as only absorb. For example, it is particular frequency in the nearby frequency in webinars increase or decrease a little bit why you you want to the absorption quite has been CPC frequency
Jin-Yi Yu: specific wavelength of CB CB radio William Penn for specific frequency and also the second part of our concept, but everything here before this slide just try to appeal to the importance. One important thing there to fact
Jin-Yi Yu: Not allow
Jin-Yi Yu: clean house care greenhouse effect to happen you know after mass political
Jin-Yi Yu: Committee, you know, atmosphere. The first fact is
Jin-Yi Yu: Really to
Jin-Yi Yu: The first fact is
Jin-Yi Yu: We install
Jin-Yi Yu: Because our solar radiation emitted by warm object. So is radiation, who are constantly I'm showing in our careers radiation emitted by a co object. So, is we installed here was his vacation or concentrate at a longer wavelength. So these will stop allow show we we install
Jin-Yi Yu: Pronounce show way and long way to happen a different frequency dependent less first fact that's why we can have
Jin-Yi Yu: We now see fact. The second factor is how atmospheric of gases.
Jin-Yi Yu: On the absorb
Jin-Yi Yu: Certain
Jin-Yi Yu: Pen, how
Jin-Yi Yu: Certain frequency pen or radiation right so Russia to these two facts together produce this greenhouse effect. And this first fact is called we use it all.
Jin-Yi Yu: In a second fact how atmospheric gases only absorb certain frequency of radiation is called selective
Jin-Yi Yu: Absorption
Jin-Yi Yu: Right. So in conclusion, we install an selective absorption
Jin-Yi Yu: To from Asian to give rise to the greenhouse effect about us.
Jin-Yi Yu: Atmosphere. So if you call to the outer premise Mars, Venus, then you have to ask yourself.
Jin-Yi Yu: To pose of this fact it is in that particular premise that the most inaccurate premise. So let me to exercise in order
Jin-Yi Yu: To allow first fact we install
Jin-Yi Yu: Not only come foo foo fighter. What is a science temperature
Jin-Yi Yu: What is that Kremlin.
Jin-Yi Yu: Can Petra, so we cannot change signs temperature, but you can break this window can remove a greenhouse effect by saying, no, I tried to another planet.
Jin-Yi Yu: And the planet was asked heated by some in the solar system still in the solar system.
Jin-Yi Yu: And then we now create another planet. This planet is so corrupted as a temperature very close to the sun, temperature, then we start tell us that
Jin-Yi Yu: Is solar radiation come to this planet and the courage radiation leaving this planet will operate at the very similar frequency. But then this pregnant cannot have greenhouse effect.
Jin-Yi Yu: And now this, we can also design a situation that
Jin-Yi Yu: We break a second
Jin-Yi Yu: The second obsession.
Jin-Yi Yu: With Bray. The second fact also can break the greenhouse effect, right. How can we change it remove this rapid absorption
Jin-Yi Yu: And then we need to design
Jin-Yi Yu: The thermosphere inside this particular premise with design we say we're going to put in some cases, some of our cases can absorb
Jin-Yi Yu: Shorter wavelengths. Some other cases can absorb longer wavelength, then the whole quarter must be in this imaginary premise.
Jin-Yi Yu: does not serve the absorption because it atmospheric gases can absorb post showing and normally. Then if you can design such a scene, then this premise does not have greenhouse effect, either. So you might get upon again now.
Jin-Yi Yu: Don't come to second path. Why selective absorption
Jin-Yi Yu: Why outermost be only absorb certain frequency, then what can you to continuously pay you have to come to a very fundamental question why agnostic guesses can absorb energy
Jin-Yi Yu: What does it take energy for right so the answer is a must read cases absorb energy from terrestrial radiation from cell radio or from any source in order to change his energy they will
Jin-Yi Yu: Right. And then we relied submit to radiation energies to absorb it to change the energy level of outcome of more occur.
Jin-Yi Yu: In the energy level of atoms or molecules are descriptive. They have certain for example you john curator is a this moral structure.
Jin-Yi Yu: Now you allow this electron to Trump or America in this modern physics. So our focus has the number is. But it this last election we jump from one
Jin-Yi Yu: Entity open to that higher energy of open that, for it is in this energy of it is energy amount of say 20 for each jump to the next level it because 37
Jin-Yi Yu: In order to jump from energy they were 22 energy there was 37 unique among the among energy unique is 37 minus 20 is 17 for example 70
Jin-Yi Yu: Joe in order to jump from one entity level code, yada. And this is energy you're quiet and we know if we want to radiate
Jin-Yi Yu: Radiation to help us do that. We know that the radiation. The energy they were related radiation is a constant edge case is frequency. Right.
Jin-Yi Yu: So this. So in order to pay some this formula, the energy among this example needs 17 has to be produced by a frequency pen that is equal to 17 divided by edge.
Jin-Yi Yu: So it's a certain frequency pen can deliver the exactly Amanda energy. This example need in order to jump from one entity level Korea.
Jin-Yi Yu: If you keep the energy. This example 18 job October 28 Joe or 15 channel or certain gel, then you will jump from one level to the other. That's why as a as is Jared question or someone's question, that why a particular frequency pen because
Jin-Yi Yu: All these frequency pen. For example, this is an example. This frequency of water vapor this energy can absorb it at a particular
Jin-Yi Yu: Frequency. Let's say 1.5 1.5 is energy level among his edge price.
Jin-Yi Yu: Of frequency is x times one divided by 1.5 millimeter and this energy provided by these frequencies happen to be the exact amount energy that water vapor need H2O
Jin-Yi Yu: You know, one over here.
Jin-Yi Yu: It's here which here.
Jin-Yi Yu: This energy among his executive among this molecule structure can be used to change his energy level. Okay. That's why it is descriptive. Now the question is, how many ends today will exist in
Jin-Yi Yu: For atmosphere, right, so here quickly.
Jin-Yi Yu: Or its energy of a molecule can be used to do forcing you to change his speed the cross movement of this molecule. So he's speaking in SPSS. Why this
Jin-Yi Yu: Give energy levels relate to this transformation, then the energy level can be continuous, because it's relatable one over two times and times.
Jin-Yi Yu: Square is velocity. However, this energy among his user base, not so that's not important. So more important higher energy level is related to the following three things of monetary
Jin-Yi Yu: Migration see here we have this edge tool as example. See this action. Oh, you're connected in this condition can vibrate vibrate back and forth, back and forth, right, and this is called vibration pen this year.
Jin-Yi Yu: So you read it to you and say, water vapor
Jin-Yi Yu: By precision pen can say, or this Teresa radiation emitted by something, something is absorbing most of the pie water vapor vibration pen. Then you realize that that
Jin-Yi Yu: Radiation we discussed in our paper is absorbed by changing how fast is H2O band can vibrate between a chill kitchen. Now that's called vibration, Ben. This is second though is stable energy and that's also related to what anybody. What is the single use
Jin-Yi Yu: To change temperature by producing vibration on a molecular level anybody
Jin-Yi Yu: Everything we used to use that seems
Juan Tolento: Microwave
Jin-Yi Yu: Microwave see my coworker remember. Oh, it
Jin-Yi Yu: Is a very long way very shortly.
Shortly, but
Ved Bhoot: On
Jin-Yi Yu: See, almost a pattern right
Jin-Yi Yu: It's so crowded radio is not going to know Teresa invalid Michael is very long way we say the longer wavelength.
Jin-Yi Yu: longer wavelength below the energy intensity. So Michael is not very, very strong. We can I use camera in our mind to heat up for
Jin-Yi Yu: Because two strands color temperature party cut costs and Michael is an average Strunk and White mcelwain is, look, please don't witness because
Jin-Yi Yu: It is very small entity, a monk, and that's why it is very long wavelength and why it is very small energy level because it is related to changing how fast the water vapor Viper H2O Viper here.
Jin-Yi Yu: So Michael way is trying to the amount of energy produced by microwave is where brands, which ties is frequency exactly match this vibration
Jin-Yi Yu: Energy level that's why my coworker here who because maybe now we can on the machine producer radiation and microwave frequency
Jin-Yi Yu: Wavelengths he happen match the vibration of water vapor and all our for has watering. So if you put something does not contain water vapor into McCoy McCoy is not gonna walk
Jin-Yi Yu: Right, because my goal is try to change the vibration and the faster the water vapor vibrate than a woman or a match. Okay. So as a name for example.
Jin-Yi Yu: The water H2O can also rotate right he don't tell faster or a smaller in as an even higher.
Jin-Yi Yu: Level energy call rotation path. So we literally can see water vapor vibration pen absorb the speed and validation or he said this, that radiation is absorbed by water vapor rotation back to a very good point.
Jin-Yi Yu: So always discussing
Jin-Yi Yu: Unless you're working with Chinese at school or a department.
Jin-Yi Yu: Head or in the
Jin-Yi Yu: Air agree know you already satellite group. Otherwise, you don't need to know radiation transfer. I don't need to know radiation transfer either
Jerry Lin: For my research question.
Jin-Yi Yu: Yes, but before you answer.
Jin-Yi Yu: But I want to make sure I can
Jin-Yi Yu: Understand what when I read the paper and they say, oh, he was absorbed by water vapor evaporation pen rotation, but I want to make sure I understand what you're talking about, even though that's notice nine bottom for my question now for my research. Yeah, please copy your question please.
Jerry Lin: Yeah. So yeah, yeah. So for all four of these storage.
Jerry Lin: Methods.
Jerry Lin: All for them. Increase the temperature of molecule right are
Jin-Yi Yu: Now, not necessary. Okay. Yeah, because
Jin-Yi Yu: Temperature molecular
Jin-Yi Yu: Is represented by his kinetic energy.
Jerry Lin: All right. Okay. Yeah.
Jin-Yi Yu: It's a motion because, for example, you
Jin-Yi Yu: Go to bed, very high amount of energy has to change in the electronic orbit, then I don't think you can is necessary refreshing temperature it is it is content as a potential temperature be changed. All right, because we already know.
Jin-Yi Yu: Temperature is the kinetic
Jin-Yi Yu: The macroscopic microscopic motion or monitor
Jerry Lin: So should see
Operation and location.
Jerry Lin: For
Jin-Yi Yu: Yeah, will be translation.
Jin-Yi Yu: My presentation, but I'm not very good in this modern physics. So I could be wrong, but I believe, based on the definition of the temperature, you should be translation.
Jin-Yi Yu: Potential and preparation any full of highest level, you know, trying to basically change as we describe the junk from for molecular level of it to the other, or be but that's why I want everybody to understand for his second absorption and then here we have further discussion about
Jin-Yi Yu: See solar energy you put energy could be used to, to change the the movement of the how fast the molecule move or how fast it located of operating on a molecular level, or is there an atomic
Jin-Yi Yu: option if you it radiation is absorbing to change that afternoon orbit, because this amount energy involved in this one is very high, so must be very, very high frequency radiation in order to produce high E
Jin-Yi Yu: The frequency has to be high in order to be high frequency must be very, very shortly. So basically, as x ray camara used to change the can, I try to open or using auto variation to change the the opposite label from when they were for the other
Jin-Yi Yu: Day when you come to any use to change the lead Rotation. Rotation of operation location of operation is technique, very low see change evaporation use my going
Jin-Yi Yu: To draw attention you're inferring change this further the RPS us the association in the produce hold them up or to personal produce all your basic facts are so
Jin-Yi Yu: Each and it today boys relate to a
Jin-Yi Yu: Particular frequency. And that's why depends on which atmospheric gases. That's why in the second week, we need to describe anytime we starting to come. We need to first ask yourself.
Jin-Yi Yu: What is the composition of matter must be we're going to have that premise, we're going to study.
Jin-Yi Yu: Because depends on what kind of cares inside. Inside that atmosphere that that premise atmosphere.
Jin-Yi Yu: It's going to come have a different story. I mean, radiation transfer and different story on the entity parents and energy Paris and energy.
Jin-Yi Yu: Distribution is going to translate into temperature distribution temperature distribution is going to affect hydrostatic in to stopping Paris Kernan motion.
Jin-Yi Yu: And master whole story of our climate. That's why we need to know the composition of our Thomas any of MSP so here you also talking about
Jin-Yi Yu: Different terminology that the absorption pen or absorption language. I'm not
Jin-Yi Yu: Going to go through and but I want you to read some of these, for example, all those are the greenhouse gases. Right. They can see that
Jin-Yi Yu: Carbon carbon of CO2, if I have an operation happen at a 50 micron or 4.2 to six micron and H2O, water vapor has a three evaporation pen.
Jin-Yi Yu: I happen to 2.73 see. So you see sometimes this absorption is not continue it just 123 ready to three particular frequency pen and then. So that's why we have
Jin-Yi Yu: Medicare. This product is a pic pick up instead of continues.
Jin-Yi Yu: But you notice one thing
Jin-Yi Yu: When he caught a lower and lower.
Jin-Yi Yu: Longer normal way can do it no energy table. They can do something more convenient for this one, Dora continues to
Jin-Yi Yu: click on Finish this chapter by telling you what is absorption nine Ben obsession is each of these descriptive obsession absorption futures an obsession and
Jin-Yi Yu: Then when you have many, many of these absorption may need each other in become
Jin-Yi Yu: Absorption pen, please. Okay, so this is not particularly important because nine column for you. My research is probably not important to many of us research.
Jin-Yi Yu: Right, but it's good that we know what it means. I put it here is because when I was a graduate student, I read a textbook of virtue. I always get confused. I always coming on.
Jin-Yi Yu: So long, to make sure you know those tonight. Okay. I want to quickly saying that radiation comes through our cameras fear, even though muscle raise up get up sorted
Jin-Yi Yu: Then if the survey. This is not an absorptive for happened too complicated happened radiation surgery. So what we're describing here is not only
Jin-Yi Yu: A product that does not do not own a prior to solar radiation is also a prior to Teresa radiation or any radiation, but so basically that radiation calling in and now in our atmosphere. That's how we call radiation transfer
Jin-Yi Yu: He can have for action happen. One is can absorptive or refracted okay scattering okay transmitted transmedia just coming in can absorb it become zero.
Jin-Yi Yu: And he didn't can absorb it. The whole atmosphere transparency, the corner with them because it changes the rationale is trouble is called transmission and but you can
Jin-Yi Yu: Be coming in his, his truck. The rational to market simple exactly coming in 30 degree here in cup cannot change the direction exactly 30 degree. Last call refraction again.
Jin-Yi Yu: And scattering means that he changed the direction of the traveling but directional traveling can be in any
Jin-Yi Yu: Angle. Okay, so here the difference between a fraction and scary refreshing light comes back from an object exactly semi ankle which encounter that object service.
Jin-Yi Yu: With exactly intensity. So energy coming country what we've tried to do it for scheduling is different story scattering you split the line into a slump or a traveling in a different direction.
Jin-Yi Yu: Or low scatter it is dispersed like both forward and backwards. The most analytical for so long. I want you to remember first thing is to know how to explain this for
Jin-Yi Yu: Action of radiation transfer and the interesting part is a scattering MC scattering is important for our camera system because of anybody know what buddy affect us.
Jin-Yi Yu: Absorption refraction transmission it determining how much energy can absorb it not absorptive is a beetle is doing refraction. Right.
Jin-Yi Yu: Snow and ice skating reflect so so this is a bit of doing this and surface ultra Luxe ocean 70% and 30% calorie tracking in transmitted means cultural elements with the rich service. What does the scattering method where I
Jin-Yi Yu: Nobody
Jin-Yi Yu: Scattering becoming the color of our life. Haha.
Jin-Yi Yu: Ricardo Lara Lara coming is a lot determined by scattered because
Jin-Yi Yu: We're on a time. So I want to finish this please bear with me for a minute. So the reason we see a car, not be so is blue and explain why it is pull
Jin-Yi Yu: Up my son, I come to how Hearst Shine on your screen. The light come in with all kind of wavelengths with blue collar white collar yellow car to car.
Jin-Yi Yu: But because the screen absorb most of our color you only allow pro card to refresh out or to get out of this group in this blue car is only kind of left
Jin-Yi Yu: All the other kind of from somewhere in the visible, I can absorb the practice with only the blue car is not absorb it, so he can send to our I
Jin-Yi Yu: But in order for our life come to your eye. If it is called student refraction, then the light has the coming exactly at an angle between your into the screen.
Jin-Yi Yu: It can reflect Semyon coco, coco I that's very difficult. So most of the kind of come to your our is because of scattering process.
Jin-Yi Yu: All this color cast gathering all the restaurant and back and forth, back and forth, so he has 360 degree possibility to go into my so all the quarter we observed is compliance so scattering process. Okay, so here
Jin-Yi Yu: You are you when we have showing. He has all kind of caught up right when Sun is overhead purpose.
Jin-Yi Yu: Then this Sunday is very close to us because in anger, because anger zero. So all the sudden I will come in Kosovo at a massive very quickly and most of kind of didn't get scattering out right so we still have quite caught up. We still have to
Jin-Yi Yu: Combine come to it. So look at the Sunday noon time is very close to my car because all caught up either get lost in the case scary.
Jin-Yi Yu: But in an known time. The sun is quite but surrounding the sun is sky, sky blue why Scottsboro the catalog sky must be something
Jin-Yi Yu: This is what I can scale it back and forth, back and forth, back and forth. And then eventually become to our eyes. So, for example, he we look to the sky in this direction.
Jin-Yi Yu: Will you find out a color is blue quite what it means means that there's a blue collar come to UI. When you look at is the direction
Jin-Yi Yu: Right, so the skies and the Europe, the other direction. Oscar is still true right now means in the whole sky, they must be a lot of product code back and forth, back and forth. So any direction up to the sky. The blue car coming in July. So you your President last broker. So why Peru, because
Jin-Yi Yu: We had sunlight coming in, for example, Ricardo yellow color green collar blue collar. For example, who is the shortest way plants. Right, so I should do research.
Jin-Yi Yu: And then to very long reverence record. And so when we do a scattering, it is it is scattering by who the son is getting by, who I am, monitor
Jin-Yi Yu: And so, which color blue or a better way, which cannot be selected refracted more guests Kevin most efficiently depends on the size of a molecule.
Jin-Yi Yu: That to the scattering in our atmosphere cases, the size is a pretty close to brew quarter wavelength. That's why our atmosphere.
Jin-Yi Yu: Pinto most effective our the most, I guess, is most capable to reflect blue hair. That's why I asked Garrett portal. So if we want to change our gut skycar to convey read question. We do anybody
Jin-Yi Yu: You want to make our atmospheric guests to become bigger size, right, what can we make the atmosphere guest speaker so we
Jin-Yi Yu: Would put this pollution we send our past, our so info, at the most, fear, then we have a lot of big it more guests there and then you will try to
Jin-Yi Yu: Scattering the logo image which is record, that's why. Remember yesterday, the day before yesterday, what did we see
Jin-Yi Yu: We see very were some other fine. Right, right, because we have five wildfire producer our arrows into this must be something
Jin-Yi Yu: In the air molecules. In fact, I must be become very big size they bring it besides coral reef scattering the longer wavelength which is record. And that's also. That's the reason we see the red sun even a known time, a few days ago. So are you to exercise this concept.
Jin-Yi Yu: Is also telling you why science, a look. Right, right. Because when he travels through atmosphere muscle blue color is already scattering by our air monitor
Jin-Yi Yu: In this local car that when it comes to your if you look for horizon order radiation coming from sun.
Jin-Yi Yu: Or the broker K scary, scary, scary roller skating was in the near horizon. So there is no chance for his broker to cope with life when it is scattering at noon time
Jin-Yi Yu: The poker is catering overhead very close to you. And then this poker cut back and forth eventual quarter right as far as crime is still pull
Jin-Yi Yu: All understand is, is very interesting.
Jin-Yi Yu: And lastly, if you study Fisker karma or strategy officer food and I mean
Jin-Yi Yu: All the question became, are saying, what kind of a masa issue here, then you say okay, it depends on how stable and stable.
Jin-Yi Yu: Our chemistry is and then you say okay what determine how Thomas private temperature distribution and the vertical direction, of course, the radiation. So now you probably
Jin-Yi Yu: Are not already absorbed in a similar sphere. And then when the baby little here and then most of the cards on a surface then you find out that based on radiation.
Jin-Yi Yu: Transfer alone. Our must be temperatures up very, very warm and extremely kokoda very quickly become not stressed very large and then increase
Jin-Yi Yu: And because this atmosphere has a love story is even larger than the trial at eight o'clock straight even cooling down faster than
Jin-Yi Yu: typically see every 10 kilometer. So this rain is very unstable when he's very unstable is going to produce one convection is going to produce connection.
Jin-Yi Yu: Is canopies woman's media server is going to ship. Up, up, up, up to warm up the upper atmosphere. So the temperature instead of look like Ricardo discard look more like this green column for you in this
Jin-Yi Yu: Column. And so this temperature at the end after it is adjust it is initially determined by radiation adjust by convection is called
Jin-Yi Yu: Radiating combated equipment temperature and this temperature is very important because when you restart the physical economy on to physical pro dynamic
Jin-Yi Yu: All the equation always come with something called that's assuming radiated come back in April state. So I want you to not get scared by the statement.
Jin-Yi Yu: Is just these statements are saying that the temperature distribution in a vertical direction that we want to study is a result of solar radiation.
