AQUA Satellite -- AIRS -- Atmospheric Infrared Sounder -- Carbon monoxide footprints

It's interesting to watch the pattern shift from north to south with the seasons. Seems like Spring and early summer gets the focus of activity, except for the occasional surges in various places - Central Africa, Central South America, SE Asia, and China put-off particularly big blasts. One thing I was surprised to see is that the US has a surprisingly low footprint most of the time... and that large blue area (carbon monoxide free?) right over India - what's with that? Interesting stuff! :-)

I was also somewhat surprised to see North America having a rather small footprint. To answer your question, I can't! IMO, I believe it is China err Tibet that have this massive, dense thermal blue footprint you mention. You might want to look into the Hadley Cell and it's affects. This map shows vapor uplift currents coming from the region, which bounce other pressure cells that also drive earth weather.

Oh the wonderment of high & low gradient spectrums uniting! :)
