An IR thermometer would probably be the best measure of effective surface temperature because it's effectively measuring Su.

I find that if you look at the black body spectrum of -40 to -60 F, and the IR spectrum's of both Co2 and Water, and then you then point a handheld IR thermometer at the sky on a clear 20 - 35F day (even accounting for it blocking longer than 14u), 333W / m2 is unlikely.

I bought myself a cheap $ 30 IR thermometer recently and was hoping somebody here could offer a possible explanation for some of the measurements I am getting.
