Idealized Canopy
qCanopy – The collection
of vegetable matter covering the
land surface is called the plant canopy.
qOver moist regions,
most of the water transferred from soil
to atmosphere moves through
vegetation.
qWater moves into the roots,
through the plant parts to leaves,
and passes into the atmosphere through stomata.
qRoot and stomata
control the exchanges between the vegetations
and the atmosphere.
qThe idealized canopy is
used to quantify the
vegetation-atmosphere fluxes via LAI and leave and
atmosphere properties.
