Collision with the surface and other molecules. Conductive and convection. Even CO2 is predominantly energetic at the surface via collisions. gettig ready for bed. may chat later. probably unlikely. I sincerely wish to carry on discussion tomorrow.

At a certain point where the abundance of molecules is less then the radiative de-excitation of molecules becomes the major mechanism in transfer of energy. That is the upper troposphere. Here radiation to space outnumbers energy exchange via collisions of molecules
