中国区域历史及未来预估径流和蒸散数据集（1985-2100）

中国区域历史（1985~2014）及未来预估（2015~2100）径流和蒸散数据集由六个CMIP6降尺度模式（CanESM5、FGOALS-g3、GFDL-CM4、IPSL-CM6A-LR、MPI-ESM1-2-HR和MRI-ESM2-0），驱动可变下渗容量（VIC）水文模型模拟得到，包括总径流深、地表径流深和蒸散发三个变量，空间分辨率为0.25°，时间分辨率为月或年。经过统计降尺度偏差校正的模式在中国区域气候模拟误差较小，基于实测气象数据驱动的VIC模型在历史期径流模拟效果较好。该数据集可为中国区域未来水资源中（SSP2-4.5）、高（SSP5-8.5）排放情景下的变化研究提供参考。

The dataset of historical (1985–2014) and future projected (2015–2100) runoff and evapotranspiration over China was developed by driving the Variable Infiltration Capacity (VIC) hydrological model with six CMIP6 downscaled models: CanESM5, FGOALS-g3, GFDL-CM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, and MRI-ESM2-0. It includes three variables: total runoff depth, surface runoff depth, and evapotranspiration, with a spatial resolution of 0.25° and a temporal resolution of monthly or annual. The models subjected to statistical downscaling and bias correction exhibit small errors in regional climate simulation over China, and the VIC model driven by observed meteorological data performs well in historical runoff simulation. This dataset can provide references for studies on changes in regional water resources in China under the medium (SSP2-4.5) and high (SSP5-8.5) emission scenarios.
