Precipitation - GPCP Monthly

Sample product image of NOAA CDR Global Precipitation Climatology Project, (GPCP) Monthly; it depicts the extent of precipitation across the globe during the month of July 2016.

This dataset provides scientific researchers a high quality Climate Data Record (CDR) of global precipitation, from the Global Precipitation Climatology Project (GPCP).

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 insitu observations. Data are provided on a 2.5 degree grid.

Note: The 1979 - August 2016 data uses both the AIRS Microwave and infrared channels, whereas the post August 2016 data use only the AIRS Infrared. The Daily and Pentad products, V1.3, are currently under development and will be released as soon as they are complete.
