NOAA Global Precipitation Climatology Centre (GPCC)
The Global Precipitation Climatology Centre (GPCC), maintained by NOAA's Earth System Research Laboratory, provides two datasets on precipitation. First is the monitoring product for the period 1986 to present, based on quality-controlled data from 7,000 stations. The second is the Full Data Product for the period 1951 to 2004, based on quality-controlled data from a larger number of stations (up to 43,000) with irregular coverage in time. This product is optimized for best spatial coverage and use for water budget studies.
Note that the gridded gauge-analysis products provided by the GPCC are not yet bias corrected for systematic gauge measuring errors. However, the GPCC provides climatological estimates for that error as well as the number of gauges used on the grid.
