``... The MSUs are cross-track scanners with measurements of microwave radiance in four channels ranging from 50.3 to 57.95 GHz
on the lower shoulder of the
Oxygen absorption band.
The CO2
absorption / emission is going
on everywhere to move heat into the nitrogen /
oxygen everywhere too, creating masses of air that rise and are displaced by cooler air, pushing the warmer air still higher up, where eventually heat is emitted into outer space.»
On the contrary they explicitly measure the
absorption by
oxygen, just in that region of the spectrum where you said it was a wild - assed guess.
I have to clarify myself
on the aspect of
oxygen and nitrogen
absorption / emission in our atmosphere.
