NCEP/CPC Four Kilometer Precipitation Set, Gauge and Radar
Listed in NASA Earthdata CMR
A prototype, real-time, hourly, multi-sensor National Precipitation Analysis has been developed at the National Centers for Environmental Prediction (NCEP) in cooperation with the Office of Hydrology (OH).
Description
This analysis merges two data sources that are currently being collected in real-time by OH and NCEP. Approximately 3000 automated, hourly rain gauge observations are available over the contiguous 48 states via the GOES Data Collection Platform, and ASOS.
In addition, hourly digital precipitation (HDP) radar estimates are obtained as compressed digital files via the AWIPS network. The HDP estimates are created by the WSR-88D Radar Product Generator on a 131 by 131 4 km grid centered over each radar site. The data analysis routines, including a bias correction of the radar estimates using the gage data, have been adapted by NCEP on a national 4 km grid from algorithms developed by OH ("Stage II") and executed regionally at NWS River Forecast Centers.
