 The study compared three satellite-based rainfall estimation methods, CMORPH, Persian, and TRMM-TMPA3B42RT, with traditional rain gauge data collected in Ethiopia. The results showed that the microwave-based TRMM-TMPA3B42RT was most accurate, followed by CMORPH and then Persian. The accuracy of the satellite-based estimates depended on the rainfall regime, with the highest accuracy observed in the northwestern region, where there is a strong ITCZ effect and high elevations. In the southeastern region, which is characterized by lowlands and a semi-arid climate, the satellite-based estimates were less accurate due to the lack of a strong ITCZ effect and lower elevations.
