Rain attenuation statistics at Kaâ€band estimated from weather radar observations in Belgium

This paper presents rain attenuation statistics for satellite-ground transmission links at Ka-band based on ten-year reflectivity observations from a C-band weather radar. The ground receiving station and the radar are both located in Belgium. Only precipitation under the freezing level is considered and the attenuation produced by hail is removed by applying a reflectivity threshold. The radar-derived attenuations are analyzed to investigate the influence of elevation and azimuthal angles on the attenuation statistics. It is shown that the azimuthal dependence is extremely low. In contrast, t... Mehr ...
