The Global Precipitation Climatology Centre (GPCC) is operated by the German Weather Service (DWD) under the auspices of the World Meteorologic Organization (WMO). It has the task of collecting global in-situ precipitation data to produce quantitative global precipitation and water balance analyses.
The "GPCC Full Data Reanalysis" contains sums of precipitation over land and is more than one hundred years long: It starts in 1891 and ends in 2016 (Version 2018). For this reanalysis quality controlled data from all globally available land stations (rain gauges) are used. The number of stations that were used to create the gridded data set has spatial and temporal variations, and is therefore included in the data set as a variable. The gridded final data set is optimized for best spatial coverage and use in water balance estimations and was used for trend analysis. This GPCC reanalysis has a higher accuracy in the precipitation data than the near real time products such as the GPCC Monitoring Product, that is available at ICDC as well. More detailed information on the methods applied for the preparation and interpolation of the original data can be taken from the cited literature.
The "GPCC Full Data Reanalysis" is available in three spatial resolutions. ICDC has provided the highest resolution of 0.25 °.
The high quality of the data is assured by the DWD. It is the most accurate data set of the GPCC. Users of the gridded data sets should take into account the number of gauges per gridpoint. According to GPCC, this data set is suitable for regional climate monitoring, model validation, analysis of climate variability and water availability. The monthly precipitation data have been checked statistically and the data flagged as questionable passed through an additional visual quality-control. In addition to that the monthly precipitation data have been checked for spatial and temporal homogeneity. More detailed information is available in the stated references.
