Abstract:

Measurements of apparent sky temperatures taken over a one-year period at 15, 17 and 35 Gc are summarized. Sky temperature profiles for various meteorological conditions are presented as well as curves showing the percentage time distributions for various zenith angles. Such factors as absorption and radiation by oxygen and water vapor, extrapolation of the data to other geographical areas, and the relation between total attenuation of the atmosphere and sky temperature are discussed. A description of the radiometers and the calibration techniques are included.
