Global Precipitation Climatology Project (GPCP) Climate Data Record (CDR), Version 1.3 (Daily)

Metadata Updated: September 19, 2023

The GPCP Daily analysis is a companion to the GPCP Monthly analysis, and provides globally complete precipitation estimates at a spatial resolution of one degree latitude-longitude and daily time scale from October 1996 to the present. Although derived using both some of the same, but also different, data sets and methods than used in the GPCP Monthly analysis, the GPCP Daily "adds up" to the GPCP Monthly. The GPCP Daily V1.3 analysis is currently computed by the University of Maryland and submitted to NCEI. The routine update of the product takes place two months after the end of the month, once all input data sets become available. The data set is part of World Climate Research Program (WCRP) and GEWEX activities, being part of the array of data sets describing the water and energy cycles of the planet under the auspices of the GEWEX Data and Assessment Panel (GDAP). Details of input data sets and methods can be found in: Huffman, G.J., R.F. Adler, M. Morrissey, D.T. Bolvin, S. Curtis, R. Joyce, B McGavock, J. Susskind, 2001: Global Precipitation at One-Degree Daily Resolution from Multi-Satellite Observations. J. Hydrometeor., 2(1), 36-50.

Licence Although large-scale time and space biases are limited by scaling the analysis to the GPCP Monthly analysis, the accuracy of individual daily estimates at fine resolution is limited. See the Algorithm Theoretical Basis Document for a description of the use limitations for this dataset.
Lineage The data were produced through a joint effort between the University of Maryland and NASA and are archived at the NOAA National Centers for Environmental Information (NCEI). See associated documentation for more information about the creation of the dataset.
