CMAP - (CPC)Climate Prediction Centers Merged Analysis of Precipitation dataset 1979-2006

Updated: 2009-11-26

The Climate Prediction Centers (CPC) Merged Analysis of Precipitation (CMAP) dataset uses a technique which produces pentad and monthly analysis of global precipitation in which observations from raingauges are merged with precipitation estimates from several satellite-based algorithms (infrared and microwave). The CSIRO version of this dataset is a concatenation of the individual monthly data files into a single contiguous netcdf file for the two sepearate time periods of 1979-2006 and 1980-1999 with a spatial resolution of 2.5° x 2.5°. The 1980-1999 version of the dataset has also been processed to include calculated Climatology and Seasonal forms of this dataset. There are approximately 4 files totaling 27.1 MB.
