The HKH Region Climate data were derived from WorldClim(http://www.worldclim.org/), This map layer shows monthly precipitation, for the period of 1950-2000. The data layers were generated through interpolation of average monthly climate data from weather stations on a 30 arc-second resolution grid. Major climate databases compiled by the Global Historical Climatology Network(GHCN),the FAO, the WMO, the International Center for Tropical Agriculture (CIAT), R-HYdronet. Monthly Precipitation data set consists of 12 raster files, one for each month, showing mean values derived from monthly precipitation readings.
