Abstract : The research done by Howard, Burch, and Williams is cited as leading up to other work concerned with the derivation of formulas for computing average absorption functions for selected wave lengths. The very real, current, problem facing the world's weather service is how best to use weather satellites, and it is pointed out that installing suitable equipment in such satellites and using them for long periods of time would make it possible to amass a wealth of information concerning the physical condition of the atmosphere, the status of the underlying surface of the earth, or the upper limits of clouds. A preliminary stage is the amassing of material with respect to the investigation of transmission or absorption of departing longwave radiation in the layer between the earth and the upper limit of the troposphere, using a great many experimental observations and radiation measurements made over various geographic regions, and under different meteorological conditions. Research has already shown that there are three basic groups of overlapping absorption belts in the real atmosphere in the longwave band of the spectrum. These have been examined and the results are presented in tabular form.
