Accurate and complete estimates of precipitation are critical to a wide variety of problems ranging from understanding the water budget to improved monitoring and prediction of climate. The Climate Prediction Center (CPC) has undertaken a comprehensive program to improve the analysis of gauge-based precipitation over the Americas on a range of space and time scales. The goal of this activity is to develop improved daily, monthly and seasonal gauge-only precipitation analysis products and applications in support of climate monitoring, climate prediction, and applied research. The approach has been incremental, by first focusing on the U.S. and then by expanding this effort to include the remainder of North, Central and South America. Several gridded daily analysis products (real-time and historical) are currently available. Detailed information such as data flows, the quality control (QC) system, analysis scheme, etc. are presented for these data sets.
