Global Precipitation Climatology Project (GPCP) Climate Data Record (CDR), Version 2.3 (Monthly) 

This dataset contains the Global Precipitation Climatology Project (GPCP) Monthly Analysis Product, version 2.3, and is a part of the NOAA Climate Data Record (CDR) Program for satellites.


This dataset consists of monthly satellite-gauge and associated precipitation error estimates, and covers the period January 1979 to the present. The general approach is to combine the precipitation information available from each of several satellite and in situ sources into a final merged product, taking advantage of the strengths of each data type. Passive Microwave estimates are based on Special Sensor Microwave Imager/Special Sensor Microwave Imager Sounder (SSMI/SSMIS) data; infrared precipitation estimates are included using Geostationary Operational Environmental Satellite (GOES) data and Polar-orbiting Operational Environmental Satellite (POES) data, as well as other low earth orbit data and in situ observations. Data are provided on a 2.5 degree grid.
