Ground-based rainfall measurements from gauges/radars often provide higher spatial and temporal sampling as well as the most direct measure of rainfall over many regions. Often such data are used for purposes of calibration, however, over regions with sufficient coverage they can provide better large-scale climate estimates than any satellite remote sensing technique. For this reason, accumulations of global gridded rain gauge data have been incorporated into several of the merged products.
This dataset is one of the intermediate products from version 2 of the Global Precipitation Climatology Project (GPCP) merged rainfall dataset.
The Global Precipitation Climatology Centre (GPCC) dataset [Rudolf et al., 1994] consists of approximately 6700 stations around the globe, which are extensively quality controlled and then interpolated into monthly area averages. This dataset is one of the component rainfall estimates used in the GPCP merged dataset [Huffman et al., 1997].
This dataset and other GPCP intermediate datasets are available through either of the following sources.
