The Global Precipitation Climatology Project (GPCP) is the precipitation component of an internationally coordinated set of (mainly) satellite-based global products dealing with the Earth's water and energy cycles, under the auspices of the Global Water and Energy Experiment (GEWEX) Data and Assessment Panel (GDAP) of the World Climate Research Program. As the follow on to the GPCP Version 2.X products, GPCP Version 3 (GPCP V3.0) beta seeks to continue the long, homogeneous precipitation record using modern merging techniques and input data sets. The GPCPV3 suite currently consists the 0.5-degree monthly. Follow-on products may be added, which consist of (1) 0.5-degree pentad, (2) 0.5-degree daily, and (3) 0.1-degree 3-hourly. All GPCPV3 products will be internally consistent. The monthly product spans 1983 - 2016. Inputs consist of the GPROF SSMI/SSMIS orbit files that are used to calibrate the PERSIANN-CDR IR-based precipitation in the span 60NS. Outside of 58NS, TOVS/AIRS estimates, calibrated by the IR estimates and the GPCC gauge analyses are used. This satelite-only estimate is then merged with GPCC gauge analyses over land to compute the final product. In addition to the final precipitation field, ancillary precipitation and error estimates are provided.

The *data access policy* is "freely available" with three common-sense caveats:
1. The data set source should be acknowledged when the data are used. The American Meteorological Society guidelines contain suggested formats for referencing data sets (https://www.ametsoc.org/ams/index.cfm/publications/authors/journal-and-bams-authors/formatting-and-manuscript-components/references/dataset-references/). Following their example for data that are dynamically updated without distinct versions:
