The Global Precipitation Climatology Centre (GPCC) is operated by the German Weather Service (DWD) under the auspices of the World Meteorologic Organization. It's mission is to collect global in-situ precipitation data to produce quantitative global precipitation analyses and water balance studies.
For the "GPCC Monitoring Product", quality-controlled station data from worldwide routine measurements (7000 to 9000 SYNOP and CLIMAT reports per month) are used to calculate the monthly precipitation over land areas. It is a routinely monthly gridded dataset that is updated on a continuous basis so that data is available approximately 2 months before the current date.
The monitoring product was calculated on the basis of GPCC's associated global precipitation climatology, which includes tens of thousands of stations, each of which relates to a specific period of time. The new Monitoring Product (V.6) was calculated by using the "Global Precipitation Climatology" (v. 2018, based on climatological normals for approximately 79,200 stations) for the period 1951-2000 as background climatology for anomaly analysis.
The GPCC Monitoring Product is suitable for all applications, that need gridded, monthly near-realtime data of high quality, such as comparisons with current satellite data.
In addition, we also have added the "GPCC Full Data Re-Analysis" to the ICDC collection, which has a higher data quality than the data monitoring product, but has not the near realtime availability.
The high quality of the data is assured by the DWD. The data contain error information starting at year 2007. Users of the gridded data sets should take into account the number of gauges per gridpoint and should apply the recommended correction factors for systematic errors.
