中国陆地实际蒸散发数据集（1982-2024）

本数据集为基于蒸散发互补方法研制的中国陆地蒸散发数据产品v2.0。输入数据包括CMFD v2的向下短波辐射、向下长波辐射、气温、湿度、风速、气压，GLASS反照率、发射率等，以及ERA5-Land地表温度等。本数据集时间跨度为1982年-2024年，空间范围为中国陆地。本数据集可为研究长时间尺度水循环和气候变化提供基础。陆地实际蒸散发 (Ea)，单位: mm/month。 时间分辨率为逐月；空间分辨率为0.1°。数据类型：NetCDF；本数据仅为陆地实际蒸散发，不含水面。

This dataset is the Version 2.0 of the terrestrial evapotranspiration data product for China developed based on the complementary evapotranspiration method. The input data include downward shortwave radiation, downward longwave radiation, air temperature, humidity, wind speed, and atmospheric pressure from CMFD v2, GLASS albedo and emissivity, as well as ERA5-Land surface temperature, etc. The temporal coverage of this dataset spans from 1982 to 2024, with the spatial scope covering terrestrial China. This dataset can provide fundamental support for studies on long-term scale water cycles and climate change. The terrestrial actual evapotranspiration (Ea) has a unit of mm/month. The temporal resolution is monthly, and the spatial resolution is 0.1°. The data format is NetCDF. This dataset only includes terrestrial actual evapotranspiration, excluding open water surfaces.
