RISEstimation 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 ...
Rainfall Estimation from Polarimetric S-Band Radar Measurements: Validation of a Neural Network Approach
Publisher: American Meteorological Society
Abstract: A procedure for the estimation of rainfall rate, capitalizing on a radar-based raindrop size distribution (RSD) parameter retrieval and neural network (NN) inversion techniques, is validated using an extensive and ...
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 ...
First Observations of Tracking Clouds Using Scanning ARM Cloud Radars
Publisher: American Meteorological Society
Abstract: racking clouds using scanning cloud radars can help to document the temporal evolution of cloud properties well before large-drop formation (weather radar ?first echo?). These measurements also complement cloud and ...
