青藏高原月尺度蒸发数据集（1979-2018）V2.0

本数据集包含1979-2018年青藏高原月尺度蒸发（包括土壤蒸发、植被蒸腾和冠层截留），空间分辨率为0.1度。数据集主要以ERA5净辐射数据和中国区域地面气象要素驱动数据集（CMFD）作为输入，利用S型广义蒸发互补原理计算得到。利用青藏高原12个涡度通量站的观测数据和7个流域（长江源、黄河源、怒江、雅鲁藏布江、黑河、羌塘、柴达木）的水量平衡数据对模型输出的蒸散发量进行了率定和验证，显示出了较高的精度。该数据集可用于青藏高原水文水资源和气候变化研究。

This dataset contains monthly-scale evaporation (including soil evaporation, vegetation transpiration and canopy interception) over the Qinghai-Tibet Plateau from 1979 to 2018, with a spatial resolution of 0.1°. It was mainly calculated using the S-shaped generalized evaporation complementary principle, with ERA5 net radiation data and the China Meteorological Forcing Dataset (CMFD) as input drivers. The model-simulated evapotranspiration was calibrated and validated using observation data from 12 eddy covariance flux stations on the Qinghai-Tibet Plateau and water balance data from 7 basins (the source regions of the Yangtze River, Yellow River, Nu River, Yarlung Zangbo River, Heihe River, Qiangtang, and Qaidam Basin), which demonstrated high accuracy. This dataset can be used for hydrology, water resources and climate change research over the Qinghai-Tibet Plateau.
