Vertical ground-based radiometric observations of the atmosphere at millimeter wavelengths

Abstract

A series of measurements of the atmosphere with ground-based radiometers is described. Radiometers at 94, 130 and 183 GHz have been employed. The 183 GHz radiometer has three double-sidebands on the sides of the water vapor line. The results of calculations for both long-term and short-term effects are presented.
