Climate Prediction Center GIS Portal
Use this tool to obtain real-time global climate monitoring products, and assessments of the origins of climate anomalies. For example, as of September 2008, you can view or download analysis of precipitation that covers a 30-year period from 1979 and is updated on a quasi real-time basis. Global gauge daily precipitation analysis is part of the NOAA Climate Prediction Center (CPC) Unified Precipitation Products Suite. The daily gauge analysis is created on a 0.5-degree lat/lon over the global land by interpolating gauge observations from ~30,000 stations. What does the January 5, 2011, precipitation map tell you about precipitation across the United States versus South America? The gauge-based daily precipitation analysis is constructed for applications in climate monitoring, climate analysis, and verifications of numerical models and satellite estimates.
