It seems to me that satellite information would read the radiation at different levels of the atmosphere for different wave lengths because the outward radiation for each wavelength depends on what gas has a spectral absorption lines at that wavelength and what it's density is as a function of altitude. Between spectral absorption lines it would actually see the surface radiation.
I don't know what methodology UAH used, nor the resolution and bandwidth of the spectrometer, but in light of the above, it seems temperature might not be a very good measure of GW from a satellite. However, total radiant energy would be easier to measure. I would think that energy output would be more meaningful and accurate than a temperature calculation since the solar input energy can be directly related to the earth output energy.
The charts in the OP show temperature. At what altitude? I wonder if any satellite survey has actually measured total radiation output over an extended period.
