Google Earth Engine——基于SM2RAIN-ASCAT 2007-2018、IMERG、CHELSA Climate和WorldClim的1公里分辨率的月降水量，单位是毫米。

Monthly precipitation in mm at 1 km resolution based on ​​SM2RAIN-ASCAT 2007-2018​​, IMERG, CHELSA Climate, and WorldClim.

​​Downscaled to 1 km resolution using gdalwarp​​​ (cubic splines) and an average between ​​WorldClim​​​, ​​CHELSA Climate​​​, and ​​IMERG monthly product​​​ (see, e.g, "3B-MO-L.GIS.IMERG.20180601.V05B.tif"). 3x higher weight is given to the SM2RAIN-ASCAT data since it assumed to be more accurate. Processing steps are available ​​here​​ . Antartica is not included.

  使用gdalwarp（三维样条）和WorldClim、CHELSA Climate和IMERG月度产品之间的平均值（例如，见 "3B-MO-L.GIS.IMERG.20180601.V05B.tif"）降尺度到1公里分辨率。由于SM2RAIN-ASCAT数据被认为更准确，所以给予了3倍的权重。处理步骤见这里。南极洲不包括在内。
