(May 2008)
GPCP produces ongoing, long-term, globally complete gridded estimates of precipitation. It merges precipitation estimates computed from satellite-based microwave, infrared, and sounding data with analyses of in situ gauge data. Monthly, pentad, and daily data sets are available for time period of 1979-present.

GEWEX INTEGRATED PRODUCT
Contact: Dr. Paula Brown
The GEWEX Integrated Product (IP) is the culmination of many GDAP-sponsored data product activities to consolidate the core components of the water and energy cycle into a single consistent dataset on a uniform grid. The IP combines precipitation, clouds, upwelling and downwelling radiative fluxes, turbulent fluxes from GPCP, ISCCP, SRB, LandFlux, and SeaFlux with ancillary surface characteristics, aerosol, and water vapor transports into a single uniform product on a 3 hour, 1 degree equal area grid spanning the 18 year period from 1998 to 2015. While the IP does not ensure consistency in all assumptions across all products, it represents our best effort at synthesizing the diverse products into a coherent set of water and energy parameters.
Available Products:
All data is currently being hosted at Colorado State University and is available via anonymous ftp server at: ftp://rain.atmos.colostate.edu/pub/pbrown/GEWEX_IP_2019/. The data is archived in 3-hourly data files in NetCDF format.
