The Global Precipitation Climatology Centre (GPCC) has been established in 1989 on request of the World Meteorological Organization (WMO). It is operated by Deutscher Wetterdienst (DWD, National Meteorological Service of Germany) as a German contribution to the World Climate Research Programme (WCRP). Mandate of the GPCC is the global analysis of precipitation on earth’s land surface based on in situ rain gauge data. These gridded analyses provide long-term means, monthly and daily totals, quantiles and a drought index.
