英文摘要	Precipitation plays an essential role in land surface processes, as a vital forcing variable of hydrology and ecosystem models. Satellite remote sensing is able to provide precipitation estimations at regional and global scales with high spatiotemporal resolutions. However, the accuracy of these products still need improvement especially at daily scale. In this study, we proposed a new method which can improve the rainfall product of the Global Precipitation Mission by using the soil moisture product of the Soil Moisture Active Passive mission over the Yarlung Zangbo River basin in the Tibetan Plateau. Compared to rain gauge observation, our method improve rainfall estimation at 97 of 108 GPM grids. Overall, the average correlation between improved GPM and in situ observation increased from 0.12 to 0.31, while the RMSE and RRMSE decreased by 1.16 and 0.42, respectively. It indicates that this approach can be used in a large scale to improve satellite-based rainfall products over the Tibetan Plateau.
