Rainfall Attenuation Investigations on the attenuation caused by rain and other hydrometers and their effects on terrestrial communications started as early as in the 1940s. Subsequently, many theoretical and experimental results were obtained and used to predict the effects of interaction between hydrometers and microwave signals. The theories for the prediction of rain attenuation on microwave signals are well established and widely used by many researchers.
