Polarimetric Radar Quantitative Precipitation Estimation

Radar quantitative precipitation estimation (QPE) is one of the primary tasks weather radars. The QPE quality was substantially improved after polarimetric upgrade This study provides an overview existing methodologies for rain and snow their operational implementation. variability drop size distributions (DSDs) a factor affecting rainfall its impact on performance various radar relations at S, C, X microwave frequency bands focuses this review. algorithms based use specific attenuation A differential phase KDP are most efficient. Their brief description presented possible ways further optimization discussed. Polarimetric techniques vertical profile reflectivity (VPR) correction longer distances from also summarized. quantification particularly challenging it demonstrated that methods measurements show good promise. Finally, article presents summary latest products available in US by integration information WSR-88D radars via Multi-Radar Multi-Sensor (MRMS) platform.
