Monthly precipitation in mm at 1 km resolution based on SM2RAIN-ASCAT 2007-2018 (https://doi.org/10.5281/zenodo.2615278). Downscaled to 1 km resolution using gdalwarp (cubic splines) and combined with WorldClim (http://biogeo.ucdavis.edu/data/worldclim/v2.0/), CHELSA Climate (https://www.wsl.ch/lud/chelsa/data/climatologies/prec/) and IMERGE monthly (ftp://jsimpson.pps.eosdis.nasa.gov/NRTPUB/imerg/gis/ see files e.g. "3B-MO-L.GIS.IMERG.20180601.V05B.tif") products. Final values are estimated as a weighted average between the four precipitation data sources; 3x higher weight is given to the SM2RAIN-ASCAT data since it assumed to be the most accurate. Processing steps are available here. Antarctica is not included.
