SitatWhen the cold air is dry the absolute humidity is very low. Therefore the air above the surface radiates effectively only at some wavelengths. It radiates more strongly than the surface at 15 um, where the CO2 emission is strongest, but at most other wavelengths the surface radiates more than the warmer air. The total radiation from the surface can therefore exceed that coming to the surface and the surface may remain colder.
