Estimation of Rainfall Based on the Results of Polarimetric Echo Classification
Publisher: American Meteorological Society
Abstract: The quality of polarimetric radar rainfall estimation is investigated for a broad range of distances from the polarimetric prototype of the Weather Surveillance Radar-1988 Doppler (WSR-88D). The results of polarimetric ...
Calibration of Dual-Polarization Radar in the Presence of Partial Beam Blockage
Publisher: American Meteorological Society
Abstract: In the presence of partial beam blockage (PBB), weather radar measurements can experience significant bias that directly compromises the accuracy of the hydrologic applications. Techniques for the calibration of the radar ...
