The Global Precipitation Climatology Centre (GPCC) is operated by the German Weather Service (DWD) under the auspices of the World Meteorological 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. On the basis of GPCC's new Global Precipitation Climatology (V. 2020) used as background climatology, based on climatological normals for ca. 84,800 stations focusing on the period 1951-2000, the Monitoring Product (V.2020) is calculated as anomaly analysis superimposed on the background climatology.
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. Further information on this data set can be found in the references.
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.
Last update of data set at ICDC: August 6, 2021
|Sum of precipitation||mm/Month|
|Number of gauges per grid||Number|
|Proportion of solid precipitation||%|
|Proportion of liquid precipitation||%|
|Absolute systematic gauge error||mm/Month|
|Relative systematic gauge error||%|
|Systematic gauge error correction factor||Factor 1 to 3|
Period and temporal resolution:
- 01/1982 to 3 months before now
Coverage and spatial resolution:
- Global, over land
- Spatial resolution: 1° x 1°, cartesian grid
- Geographic longitude: 0°E to 360°E
- Geographic latitude: -90°N to 90°N
- Dimension: 360 columns x 180 rows
- Altitude: following terrain
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.
