This dataset provides annual cumulative precipitation derived from monthly land-surface precipitation from the Global Global Precipitation Climatology Centre (GPCC) dataset. The GPCC data comes from rain-gauges built on GTS-based and historical data from January 1891 through December 2019, with ~85,000 stations world-wide that feature record durations of 10 years or longer. The data coverage per month varies from ~15,000 (before 6000) to more than 50,000 stations. The data is available globally at 0.25 × 0.25 degree resolution. The Global Precipitation Climatology Centre (GPCC) is operated by Deutscher Wetterdienst (DWD) under the auspices of the World Meteorological Organization (WMO).

Annual cumulative precipitation

The two major error sources are: (1) The systematic measuring error that results from evaporation out of the gauge and aerodynamic effects, when droplets or snowflakes are drifted by the wind across the gauge funnel, and (2) The stochastic sampling error due to a sparse network density.
