青藏高原七大河流源区径流深、蒸散发数据集（TPRED）

通过构建耦合积雪、冻土、冰川等冰冻圈水文物理过程的WEB-DHM模型（Water and Energy Budget-based Distributed Hydrological Model），定量解析了青藏高原七大主要河流（黄河、长江、湄公河、怒江、雅鲁藏布江、恒河和印度河）源区的水资源时空动态与驱动机制，模拟生成了各流域1998~2017年逐月、5km水资源数据产品（包括径流、蒸发）（简称为TPRED）。

By developing the WEB-DHM model (Water and Energy Budget-based Distributed Hydrological Model) which couples the hydrological and physical processes of the cryosphere such as snow cover, frozen soil, and glaciers, this study quantitatively analyzed the spatiotemporal dynamics and driving mechanisms of water resources in the source regions of the seven major rivers on the Qinghai-Tibet Plateau: the Yellow River, Yangtze River, Mekong River, Salween River, Yarlung Zangbo River, Ganges River, and Indus River. Additionally, monthly, 5-kilometer resolution water resource data products (including runoff and evaporation) for each basin from 1998 to 2017 were generated, and this dataset is abbreviated as TPRED.
