ChinaWR: a high-resolution (1 km) and long-term (1980-2020) gridded water resources dataset for China

We develop a new water resources dataset for China, referred to as ChinaWR, providing 1 km and monthly estimates of surface, groundwater, and total water resources (SWR, GWR, and TWR) from 1980 to 2020. ChinaWR was generated using a random forest model based on high-resolution (prefecture-level) data reported in the Water Resources Bulletins of China. All the data are stored in NetCDF files. The file naming format follows the template ChinaWR_VV_SSSdeg_YYYYMM.nc (e.g., ChinaWR_SWR_010deg_198001.nc), where VV represents the variable name, SSS indicates the spatial resolution (with the decimal point omitted), YYYY denotes the four-digit year, and MM represents the two-digit month. For more detailed information, please refer to the attributes of each NetCDF file.Any questions please feel free to contact: [e-mail]

本研究构建了一款面向中国的新型水资源数据集，命名为ChinaWR。该数据集提供了1980年至2020年间、空间分辨率为1千米的月度地表水资源（Surface Water Resources, SWR）、地下水资源（Groundwater Resources, GWR）及总水资源（Total Water Resources, TWR）估算结果。ChinaWR数据集基于中国水资源公报发布的高分辨率（地级行政区尺度）数据，通过随机森林模型生成。所有数据均存储为NetCDF格式文件。数据集文件命名遵循模板 ChinaWR_VV_SSSdeg_YYYYMM.nc（示例：ChinaWR_SWR_010deg_198001.nc），其中VV代表变量名称，SSS表示空间分辨率（省略小数点），YYYY为四位年份编码，MM为两位月份编码。如需获取更详细的信息，请查阅各NetCDF文件的属性字段。如有任何疑问，欢迎联系：[e-mail]
