Notes:

• Cities grouped by region; nothern (black) and northeastern (purple) cities are put together on the first plot for convenience. Western and central cities are not plotted at the moment.
• Colour of marker indicates the species for which the highest API value was attained (in most cases this is TSP).
• Note that different scales are used for the different regions!
• This plot should be updated at 19:00 JST each day, unless data is unavailable.
