Main content

The GPCC provides gridded gauge-analysis products derived from quality controlled station data. Two products are for climate: (a) the Full Data Reanalysis Product  (1901-2010) is recommended for global and regional water balance studies, calibration/validation of remote sensing based rainfall estimations and verification of numerical models, and (b) the VASClimO 50-Year Data Set which is for climate variability and trend studies. The products are not bias corrected for systematic gauge measuring errors. However, the GPCC provides estimates for that error as well as the number of gauges used on the grid.

Key Strengths

Key Strengths

Large number of stations used; gauge network extends beyond GHCN

Key Limitations

Key Limitations

Variable number of stations per grid over time can be a major inhomogeneity source.

Monitoring products are frequently updated but climate products are not

Expert Developer Guidance

Expert Developer Guidance

The GPCC Full Data Reanalysis uses the complete GPCC station database (ca. 64.400 stations with at least 10 years of data) available at the time of analysis and therefore is recommended to be used for global and regional water balance studies, calibration/validation of remote sensing based rainfall estimations and verification of numerical models. When interpreting applications and assessments based on GPCC Full Data Reanalysis users should carefully take into account the number of stations available for a specific analysis grid in a specific month.
