Estimates of Satellite-to-Earth Microwave Attenuation by Cloud, Rain, Oxygen, and Water Vapor,

Abstract

This paper provides estimates of attenuation of space-to-earth radar transmissions due to cloud, rain, and gaseous factors. Attenuation of microwaves of 58-62 GHz and 92-96 GHz are examined. Attenuations through the atmosphere for elevation angles of 50.69 deg. to 90 deg are calculated and 50, 95, and 99 percentile levels provided. Estimates are based on climatological frequencies of cloud amounts, rain rates, and water vapor, and are provided for two locations: one high-latitude temperate; the other, tropical. (Author)
