Evaluation of rain cell models using Indonesian meteorological radar data

Abstract

Frequencies above 10 GHz are strongly affected by attenuation phenomena due to atmospheric impairments, among which rain plays the dominant role. Horizontal structure of rain fields is very complex due to its high space-time variability. Considering modelled cells which are described by a small number of parameters that would allow reduced computing time, storage problems, and multiply the system simulations to optimally define the system parameters. Radar image with range bin pixel up to 200 m, 0.5 degrees of elevation angle and about 100 km from radar site. Peak of rain intensity and the distances along elliptic shape of rain cells can obtained and also each model parameters. The EXCELL and HYCELL model has been fitted and compared to every rain cell. The result shows HYCELL model has good performance than EXCELL model.
