Global monthly water scarcity indices

The three zip folders represent: 1) total water resources (wsi_total.zip), 2) surface water resources (wsi_sw.zip), and 3) groundwater resources (wsi_gw.zip). Each zip folder contains 26 global raster files (GeoTiffs) at a resolution of 0.5 degrees: - 12 monthly averages over a decade and - 1 consumption-weighted annual average of the monthly values - both for either 1981-1990 or 2001-2010. More details on the water scarcity index can be found in the corresponding article. The article is open access and can be downloaded from the link below. (Changes between version 1 and 2: Surface and groundwater data were added.)

本数据集包含三个压缩包，分别对应：1）总水资源（wsi_total.zip）、2）地表水（wsi_sw.zip）及3）地下水（wsi_gw.zip）。每个压缩包均内含26份分辨率为0.5度的全球栅格文件（GeoTiffs），具体包括两类数据：其一为对应十年时段（1981-1990年或2001-2010年）内的12个月度平均值；其二为基于该时段内月度值计算得到的消费加权年度平均值。有关该水资源短缺指数（water scarcity index）的详细信息可参阅配套开源学术文章，可通过下方链接下载获取该文章。（版本1至版本2的更新说明：新增地表水与地下水数据集。）
