Application of the SC EXCELL model for rain attenuation prediction in tropical and equatorial regions

The aim of this paper is to provide additional information about the performance of the SC EXCELL model, specifically when applied to the prediction of rain attenuation in equatorial and tropical regions. The model generates a long-term rain attenuation Cumulative Distribution Functions (CDF) that separately accounts for stratiform and convective precipitation. The model assessment in estimating attenuation CDFs due to rain are carried out against experimental data for three particular South-East Asian regions, namely Kuala Lumpur, Singapore and Thailand. The overestimation outcomes of the model suggest that to correctly predict rain attenuation on satellite communication links, the concurrency between rain attenuation and rain intensity measurement should be taken into account.
