Evaluation and Hydrological Application of Four Gridded Precipitation Datasets over a Large Southeastern Tibetan Plateau Basin

Reliable precipitation is crucial for hydrological studies over Tibetan Plateau (TP) basins with sparsely distributed rainfall gauges. In this study, four widely used products, including the Asian Precipitation Highly Resolved Observational Data Integration Towards Evaluation of water resources (APHRODITE), High Asia Reanalysis (HAR), and satellite-based estimates from Global Measurement (GPM) Tropical Rainfall Mission (TRMM), were comprehensively evaluated by combining statistical analysis simulation Upper Brahmaputra (UB) River Basin TP during 2001–2013. respect to assessment, overall performances GPM HAR are comparable each other, both superior other two datasets. For daily monthly GPM-based streamflow simulations perform best not only at UB outlet very good results, but they also illustrate satisfactory results Yangcun Lhasa stations within UB. Runoff using performs well outlet, whereas it shows poor stations. The simulated based on APHRODITE TRMM show Generally, an encouraging potential hydro-meteorological investigation UB, although some bias in flood simulation.
