Evaluation of three gridded potential evapotranspiration datasets for streamflow simulation in three inland river basins in the arid Hexi Corridor, Northwest China
Study region: This study focuses on three data-limited inland river basins in the arid Hexi Corridor, Northwest China.Study focus: The lack of ground-based observation data for estimating potential evapotranspiration (PET) usually limits the streamflow simulation.This study explored the feasibility of using three gridded PET datasets (GLDAS, GLEAM,
