Description:
Abstract: Unified global gauge daily precipitation analysis is part of the CPC Unified Precipitation Products Suite. The daily gauge analysis is created on a 0.5olat/lon over the global land by interpolating gauge observations from ~30,000 stations. As of September, 2008, the analysis covers a 30-year period from 1979 and is updated on a quasi real-time basis. The Optimal Interpolation (OI) algorithm is applied, with consideration of orographic effects in precipitation. Drs. Pingping Xie, Mingyue Chen, and Wei Shi are the primary members of the CPC working group in charge of the construction of this data set.
Purpose: The gauge-based daily precipitation analysis is constructed for applications in climate monitoring, climate analysis and verifications of numerical models and satellite estimates.

Overview Description:
Entity and Attribute Overview: The primary parameters are daily precipitation amounts expressed in mm/day. These data are prduced with input guage station data from Global Telecommunications System (GTS), data sets from River Forecast Centers (RFC), National Climatic Data Center (NCDC), as well as collections from international meteorological agencies in Mexico, South America and Australia.
