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.
This dataset consists of a combination of rain gauge data from the Global Historical Climate Network (GHCN) [Vose et al., 1992] and the Climate Anomaly Monitoring System (CAMS) [Ropelewski et al., 1984]. 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.
