 The study compared three satellite-based rainfall estimation methods with traditional rain gauge data in Ethiopia. The results showed that the microwave-based products TMPA3B42RT and CMRPH were more accurate than the infrared-based product Persian. The bias in the satellite rainfall estimates depended on the rainfall regime and elevation. At low elevations, TMPA3B42RT and CMRPH tended to overestimate rainfall while Persian tended to underestimate it. At higher elevations, however, all three SREs gave reasonably accurate results. Additionally, the study found that the accuracy of the SREs was influenced by the ITCZ effect in the northwestern part of the country where TMPA3B42RT and CMRPH tended to overestimate rainfall at low elevations and give reasonably accurate results at high elevations while Persian tended to underestimate rainfall at both low and high elevations.
