Abstract

Abstract: In an attempt to verify the feasibility of substituting ground observation data with satellite precipitation data, the accuracies of TMPA 3B43V7 and GPM IMERG satellite precipitation products in the Three Gorges Basin were evaluated by statistical analysis based on the observation data from ground sites. The results reflected that TMPA and IMERG showed good consistency. In the upper flat area of the Three Gorges Region with low latitude, the accuracies of satellite precipitation products were poor, whereas in the alpine-gorge area in the lower reach of the Region, the latitude was higher, and the accuracies were better. Satellite precipitation products have the potential of replacing ground site precipitation data, and are applicable in the study basin.
