GPCC Global Precipitation Climatology Centre monthly precipitation dataset from 1901-present is calculated from global station data. Three datasets are provided here. First is the monitoring product for the period 2007 to present, based on quality-controlled data from 7,000 stations. The second is the Full Data Product (V6)for the period 1901 to 2010, based on quality-controlled data from from 67,200 stations world-wide that feature record durations of 10 years or longer. This product contains the monthly totals on a regular grid with a spatial resolution of 0.5° x 0.5°, 1.0° x 1.0°, and 2.5° x 2.5° latitude by longitude. Precipitation anomalies at the stations are interpolated and then superimposed on the GPCC Climatology V2011 in the corresponding resolution.
