DataSetQuality:
Gridbox-by-gridbox estimates of random error are under development. A current scheme does not exist for a similar estimate of bias. However, the Monthly GPCP Satellite-Gauge estimates are constructed using calibration to state-of-the-art climatologies. Validation studies are being undertaken where sufficient data exist, mostly over land, with some coverage in tropical ocean regions.

Summary:
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 Exchange (GEWEX) Data and Assessment Panel (GDAP) of the World Climate Research Program. As the follow on to the GPCP Version 1.3 One Degree Daily product, GPCP Version 3 (GPCP V3.1) seeks to continue the long, homogeneous precipitation record using modern merging techniques and input data sets. The GPCPV3 suite currently consists of the 0.5-degree Monthly and 0.5-degree Daily. Additional products may be added, which consist of (1) 0.5-degree pentad and (2) 0.1-degree 3-hourly. All GPCPV3 products will be internally consistent. The Daily product spans June 2000-December 2019. Inputs consist of GPM IMERG in the span 55\302\260N-S, and TOVS/AIRS estimates, adjusted climatologically to IMERG, outside 55\302\260N-S. The Daily estimates are scaled to approximately sum to the Monthly value at each 0.5\302\260 grid box. In addition to the final precipitation field, probability of liquid precipitation estimates are provided globally.
-
Validation_Data:
Validation of the GPCPV3 data sets is currently in process. Previous validation efforts for GPCPV2.2 included comparisons with high-density rain gauge data sets (not part of the GPCC gauge analysis) and PACRAIN atoll gauges.

source:
The GPM IMERG V06B Final, TOVS, and AIRS V6 IR-only L2G daily estimates and GPCP V3.1 Monthly estimates all enter the analysis as pre-computed precipitation fields. See the ATBD for more information.
