On the Use of Dual-Polarized C-Band Radar for Operational Rainfall Retrieval in Mountainous Areas

摘要: AbstractRadar-rainfall estimation is a complex process that involves several error sources, some of which are related to the environmental context. The presence orographic obstacles heavily affects quality retrieved radar products. In relatively flat terrain conditions, dual-polarization capability has been proven either increase data or improve rainfall estimate. potential benefit using polarimetric techniques for precipitation retrieval evaluated here coming from two systems operating in Italy under complex-orography conditions. analysis outlines encouraging results might open new scenarios operational applications. Indeed, applied algorithm employing specific differential phase mostly outperformed examined reflectivity-based except analyzed winter storm. latter case, likely contamination by frozen melting snow tended degrade performance Kdp-based...
