CPC Global Unified Gauge-Based Analysis of Daily Precipitation
The CPC Unified Gauge-Based Analysis of Global Daily Precipitation dataset offers daily precipitation estimates over land from 1979 to the present. Developed by NOAA's Climate Prediction Center (CPC), it leverages an optimal interpolation technique to combine data from a global network of rain gauges, with over 30,000 gauges contributing to the retrospective version (1979-2005) and around 17,000 to the real-time version (2006-present). Data is provided at a 0.5-degree resolution and includes bot
