Atmospheric effects upon the radiometric determination of surface temperature were studied for channels centered at 3.7, 11 and 12 Μm. The error due to the atmosphere is least for the channel centered at 3.7 Μm, which is a real advantage. The use of a linear combination of two or all three of these channels allows one to eliminate most of the atmospheric effect. If instrumental noise of from 0.1 to 0.2 K is accounted for in each channel, the best results are obtained by a combination of the two channels at 3.7 and 12 Μm.
