Large-Sample Evaluation of Two Methods to Correct Range-Dependent Error for WSR-88D Rainfall Estimates
Publisher: American Meteorological Society
Abstract: The vertical variability of reflectivity is an important source of error that affects estimations of rainfall quantity by radar. This error can be reduced if the vertical profile of reflectivity (VPR) is known. Different ...
Evaluation of Anomalous Propagation Echo Detection in WSR-88D Data: A Large Sample Case Study
Publisher: American Meteorological Society
Abstract: A method of detecting anomalous propagation echo in volume scan radar reflectivity data is evaluated. The method is based on a neural network approach and is suitable for operational implementation. It performs a classification ...
Identification of Vertical Profiles of Reflectivity from Volume Scan Radar Data
Publisher: American Meteorological Society
Abstract: The vertical variability of reflectivity in the radar beam is an important source of error that interferes with a reliable estimation of the rainfall rate by radar. This source of error can be corrected if the vertical ...
Three Methods to Determine Profiles of Reflectivity from Volumetric Radar Data to Correct Precipitation Estimates
Publisher: American Meteorological Society
Abstract: The vertical variability of radar reflectivity reduces the reliability of precipitation estimation by radar, especially in complex orography. This important source of error can, at least partially, be corrected for, if the ...
Identification of Rain-Rate Profiles from Radar Returns at Attenuating Wavelengths Using an Inverse Method: A Feasibility Study
Publisher: American Meteorological Society
Abstract: Attenuation in rainfall is recognized as one of the most significant limitations in rain-rate estimation from weather radar returns at X- or C-band wavelengths. This paper introduces a radar measurement correction as an ...
Hydrologic Visibility of Weather Radar Systems Operating in Mountainous Regions: Case Study for the Ardèche Catchment (France)
Publisher: American Meteorological Society
Abstract: A simulation procedure has been developed for use in predetermining the expected quality of rain-rate estimates that a given weather radar system operating in a mountainous region may obtain over a given hydrologic catchment. ...
