Abstract
The paper presents and discusses a multiyear rain
rate and concurrent attenuation propagation database at Kaband
in a Earth-Satellite link. Data is analysed in several
temporal scales from hourly, monthly, seasonally to yearly
periods concerning mainly variability issues. General local rain
climate issues are highlighted. Long term seasonal attenuation
distributions are also compared to the concurrent rain
attenuation and some discrepancies discussed. The attenuation
cumulative distributions prediction using ITU model and the
locally measured rain rate is presented and discussed.
