>'Langley himself in a later memoir showed that the full moon, which certainly does not possess any sensible heat-absorbing atmosphere, has a "mean effective temperature" of about 45 C.'
This seems to be incorrect. The mean temperature of the moon is somewhere between 104-215K:
>'The mean temperature at the equator is 215.5 K with an average maximum of 392.3 K and average minimum of 94.3 K ( Fig. 19 ), representing an average change in temperature of ∼300 K. Average maximum and minimum temperatures in the polar regions (poleward of 85 °) are 202 K and 50 K respectively with a mean average temperature 104 K.'

- phaemon 10y agoI believe he was attempting to find the temperature of the sunlit moon, so was actually much too low. If you're interested, there's some discussion of it here: http://www.jstor.org/stable/1638754 http://www.jstor.org/stable/1638754
- nonbel 10y agoWhats the headline number in that article? Btw, I get ~310-320K average for the dayside, depending on albedo, etc assumptions. So 273 + 45 = 318 K is pretty close.
