Evaluation of Three High-Resolution Remote Sensing Precipitation Products on the Tibetan Plateau

Remote sensing precipitation products provide rich data for ungauged basins. Evaluating the accuracy and detection capability of remote is crucial before application. In this study, an index system in terms quantitative differences, capturing capacity distribution was constructed to evaluate three products, TRMM 3B42 V7, GPM IMERGE Final CMORPH V1.0, at various temporal spatial scales on Tibetan Plateau from 2001 2016. The results show that correlations among were larger monthly scale than annual scale. lowest between observation found December. performed best scales.
