Really? Water vapor is hardly considered in the models...but the suns photon energy is 164 W/M2, unfortunately thats all thats really been measured. We dont know the true effects of solar wind or lack there of.
Seems like the solar wind might tweak the atmosphere. The results of it can be seen in the visible spectrum. Photon radiation definitely heats the planet. However, it is unknown to what extent. And heat, IR, is only a narrow band of the broader Sun spectrum.
