Abstract
The Microwave Weather Project forms part of an overall Radio Systems Development Project which seeks to optimize the spacecraft-to-ground communications link. Statistical correlations of weather and communications capability at X- and K-bands are needed to provide practical statistical prediction of the performance of the Deep Space Network at X-band and, in the future, at K-band. A previous article discussed the general approach of the project, the measurements, calibrations, equipment, and methods. This article summarizes the results of the Weather Project for 1971 through 1974, Computed results of increases in system temperature due to atmospheric effects are plotted as functions of time, frequency, elevation angle, etc. Comparisons are made with theoretical predictions derived from a contractor report submitted to JPL, which calculated signal attenuation due to cloud cover from meteorological measurements,
