As to the effect
mentioned in your comment, as I understand it, cumulus clouds reflect infrared
radiation back into
space while cirrus clouds catch infrared
radiation leaving earth and reflect it back to earth.
I never see Rayleigh or Mie scattering
mentioned, although it is my understanding that, in the atmosphere these equations govern the absorpsion and scattering of electomagnetic
radiation from the sun, and the «long wave»
radiation of the earth back to
space.
