The National Weather Service's Climate Prediction Center (CPC) produces a Global Unified Daily Precipitation product from 1971-present. This product is the combination of all sources available to CPC with the goal of providing high quality and consistent precipitation data and offer a comprehensive view of precipitation patterns worldwide. This product combines precipitation data from sources including rain gauge measurements, satellite observations, and numerical weather prediction models. This product serves as a valuable resource for meteorologists, climatologists, hydrologists, and other stakeholders, enabling them to analyze and understand precipitation trends, anomalies, and potential impacts on weather and climate systems. The daily precipitation products are provided as aggregated 1, 2, 3, 6, 9, and 12-month accumulation periods with a 3-5 day latency.
Drought is defined as the lack of precipitation over an extended period of time, usually for a season or more, that results in a water shortage. Changes in precipitation can substantially disrupt crops and livestock, influence the frequency and intensity of severe weather events, and affect the quality and quantity of water available for municipal and industrial use.
