怒江水资源时空分布数据集（1998-2017）

本数据是基于气象观测数据、水文站点数据，结合各种同化数据和遥感数据，通过耦合积雪、冰川和冻土物理过程的青藏高原多圈层水文模型系统WEB-DHM（基于水和能量平衡的分布式水文模型）制备生成，时间分辨率为月尺度，空间分辨率为5km，原始数据格式为ASCII文本格式，数据种类包括格网径流与蒸发（若蒸发小于0,则表示凝华；若径流小于0，则表示当月降水小于蒸发）。若asc无法在arcmap中正常打开，请将asc文件前5行顶格。

This dataset was generated based on meteorological observation data, hydrological station data, various assimilation data and remote sensing data, using the multi-sphere hydrological modeling system WEB-DHM (Distributed Hydrological Model based on water and energy balance) for the Qinghai-Tibet Plateau, which couples the physical processes of snow cover, glaciers and frozen soil. It has a monthly temporal resolution and 5 km spatial resolution, with the original data format being ASCII text. The data categories include grid runoff and evaporation: if evaporation is less than 0, it indicates sublimation; if runoff is less than 0, it means that the monthly precipitation is less than evaporation. If the .asc files fail to open properly in ArcMap, please left-align the first 5 lines of the .asc files.
