Regional polarimetric quantitative precipitation estimation over South Carolina

Quantitative precipitation estimation (QPE) continues to be one of the principal objectives for weather researchers and forecasters. The purpose of this research is to present the development of a regional dual polarization QPE process known as the RAdar Multi-Sensor QPE (RAMS QPE). This scheme applies the dual polarization radar rain rate estimation algorithms developed at Colorado State University into an adaptable QPE system. The methodologies used to combine individual radar scans, and then merge them into a mosaic are described. The implementation and evaluation is performed over a domain that covers South Carolina for a severe rainfall event occurring October 2, 2015 through October 4, 2015. The QPE precipitation fields evaluated in this analysis will stem from the dual polarization radar data obtained from the local NWS WSR-88DP.
