Abstract
The National Weather Service (NWS) produces radar-derived estimates of rainfall using data collected in real time from its network of doppler weather radars. These estimates, along with observations from automated rain gauges, are used to create high resolution gridded precipitation estimates suitable for various hydrologic applications. The NWS Southeast River Forecast Center (SERFC), located in Peachtree City, Georgia, produces these estimates for the Southeastern United States, including all of the watersheds in Georgia. The current methodology for creating these estimates, called Stage III, is being improved to address radar bias issues and to add new capabilities. The new program, called the River Forecast Center (RFC)-wide Mulitisensor Precipitation Estimator (MPE), will be installed in summer 2001. RFC-wide MPE will provide an optimal estimate of precipitation which has fallen during a given clock hour. The analysis is carried out on the Hydrologic Rainfall Analysis Project (HRAP) grid, which is a polar stereographic map projection with approximately 4 km resolution in mid-latitudes.
