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 V3.3 analysis is currently computed by the University of Maryland and submitted to NCEI. For GPCP V3 daily precipitation, the primary outputs include daily precipitation rates and the probability of liquid phase. 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). This dataset provides the basis for analysis of precipitation means and variations from the global scale to regional scales with a daily time resolution and uses both satellite and in situ precipitation observations.

See associated documentation for more information about the creation of the dataset. The GPCP Daily code is made up of around 150 individual code files, which are distributed among 6 modules of code plus another 4 codes to create file listings and perform pre- and post processing diagnostics. The code is run by a single driver code (shell script)in the main directory that mirrors the monthly code (GPCPcdr_ECPd_Process1month.sh) that performs a check that all data is present and then calls each of the constituent parts of the processing code.
