Abstract: The effects of the atmosphere on radio propagation at frequencies of 10 GHz to 30 GHZ include attenuation and depolarization by precipitation, absorption by water vapor and oxygen, and multipath fading related to refractivity gradients in stratified layers. Information is presented on the probable magnitude of the various weather-related effects, considering the differences in radio frequency, geographical location, and climate. The limitations of climatological data are discussed, as well as methods of using the available data in system engineering.
