Attenuation due to rain is an important propagation effect which must be considered in the design of satellite telecommunication systems. The attenuation by rain depends on the temperature, size distribution, terminal velocity and shape of raindrops. The rain attenuation can be measured quite accurately by means of satellite beacon signals and radiometers. However, since propagation experiments are carried out only in a few places in the world and for a limited number of frequencies and link geometry, their results cannot be directly applied to all sites. For this reason, several attenuation models based on physical facts and using available meteorological data, have been developed to provide adequate inputs for system margin calculations in all regions of the world.
