10. Digest of the emission spectrum What matters, for each part of the spectrum, is the temperature at the height above which the atmosphere is transparent. Water (vapour) absorbtion bands: saturated as far as the vapour rises. Eq’m vapour pressure strongly controlled by T, so temperature of vapour emission somewhat buffered. !!Water clouds are much more delicate to assess …… CO2 bands: saturated to Stratosphere. Average T of emission only sensitive at edge of these bands, but these are quite broad. !!This does assume the stratosphere temperature is insensitive. Under query. Atmospheric windows: anything which does scatter IR here will have a strong effect per molecule. CH4, CFC’s act in this way.
