Global Precipitation Climatology Project (GPCP).
World Data Center for Meteorology, Asheville
Global analyses of monthly precipitation derived from satellite and surface measurements.
World Data Center A (WDC) for Meteorology, Asheville is one component of a global network of discipline subcenters that facilitate international exchange of scientific data. Originally established during the International Geophysical Year (IGY) of 1957, the World Data Center System now functions under the guidance of the International Council of Scientific Unions (ICSU).
The WDC for Meteorology, Asheville is maintained by the U.S. Department of Commerce, National Oceanic and Atmospheric Administration
(NOAA) and is collocated and operated by the National Climatic Data Center (NCDC).
In accordance with the principles set forth by ICSU, WDC for Meteorology, Asheville acquires, catalogues, and archives data and makes them available to requesters in the international scientific community. Data are exchanged with counterparts, WDC for Meteorology, Obninsk and WDC for Meteorology, Beijing as necessary to improve access. Special research data sets prepared under international programs such as the IGY, World Climate Program (WCP), Global Atmospheric Research Program (GARP), etc., are archived and made available to the research community. All data and special data sets contributed to the WDC are available to scientific investigators without restriction.
1DD RELEASED AS AN OFFICIAL GPCP PRODUCT, AUGUST 18, 2000
The GPCP One-Degree Daily Precipitation Data Set (1DD Data Set) provides daily, global 1x1-deg gridded fields of precipitation totals for the 3-year period January 1997 through the delayed present. The 1DD draws upon several different data sources covering different areas of the globe. Every attempt has been made to make the complete record homogeneous, given the different available input sources.
Please read the 1DD documentation for complete information.

GPCP VERSION 2 RELEASED AS AN OFFICIAL GPCP PRODUCT, AUGUST 18, 2000
The GPCP Version 2 Combined Precipitation Data Set (Version 2 Data Set] provides monthly, global 2.5x2.5-deg gridded fields of two products, the combined satellite-gauge precipitation estimate and the combined satellite-gauge precipitation error estimate. It covers the 21-year period January 1979 through the delayed present. Since no single satellite data source spans the entire data record, the product draws upon many different sources covering different times and regions within the data record. Every attempt has been made to make the complete record homogeneous, given the different available input sources.
Please read the Version 2 documentation for complete information.

Experimental GPCP Pentad (5-Day) Precipitation Analysis
An analysis of global pentad (5-day) precipitation has been constructed for the Global Precipitation Climatology Project (GPCP). It is created on a 2.5 degree latitude/longitude grid and covers a period from 1979 to near current time. This pentad analysis is a companion to the version 2 product of the GPCP global monthly precipitation analysis. Users are recommended to utilize the GPCP monthly analysis for applications of monthly and longer time scales and use this pentad data set only for studies where sub-monthly and intra-seasonal phenomena are involved.
Please read the Pentad documentation for complete information.

Please note: GPCP VERSION 1c SUPERSEDED BY VERSION 2, AUGUST 18, 2000
The GPCP Version 1c Combined Precipitation Data Set (Version 1c Data Set) has been replaced by the Version 2 Data Set. Version 2 provides significant enhancements compared to Version 1c. This archive is being provided temporarily to help users bridge to Version 2.
Please read the Version 1 documentation for complete information.
