Simulation of Different Cloud Attenuation Methods

Tropical regions normally experience heavy rain and good water content clouds. Being India a tropical country, where convective rain and cumulonimbus clouds are common factors. These two causes a major degradation in the performance of satellite systems particularly at higher frequencies. In this study, calculation of cloud attenuation using different methods are like Altshuler and Marr, Salonen and Uppala, DAH and ITU-R Models are discussed. These models are compared for different frequencies and elevation angles. Rain attenuation, cloud attenuation using ITU – R method for the city of Chennai is compared with dependent parameters.
