Bragg Scatter Detection by the WSR-88D. Part I: Algorithm Development

Introduction to the WSR-88D (NEXRAD) for Ornithological Research

The system of Doppler weather surveillance radars known as WSR-88D or more popularly as NEXRAD helped transform radar ornithology in the United States into a field that today attracts considerable attention from scientists and laypersons alike. As interest in ornithological applications of WSR-88D grows, so does the need to provide perspective on its use. In this paper, we introduce WSR-88D and...

Rainfall Measurements with the Polarimetric WSR-88D Radar

Analysis and Improvements to the WSR-88D Storm Cell Tracking Algorithm

Studies on the efficacy of storm tracking algorithms have focused upon tracking the centroids of the radar features as identified by a separate identification algorithm. Therefore, the tracking skill becomes dependent upon the behavior of the identification algorithm. In addition, the tracking results are often compared against tracks that are determined by small quantities of subjective, human...

P4.8 Performance of a New Velocity Dealiasing Algorithm for the Wsr-88d

Improving the quality of the base velocity data in the WSR-88D is an ongoing effort (Crum et al. 1998). Although the current velocity dealiasing algorithm (VDA) in the WSR-88D Radar Product Generator (RPG) generally performs well, this is not always the case. In particular, when the WSR88D is operating in Volume Coverage Pattern (VCP) – 31 (the low-Nyquist clear-air mode; Federal Meteorological...

Rainfall Estimation with a Polarimetric Prototype of WSR-88D

As part of the Joint Polarization Experiment (JPOLE), the National Severe Storms Laboratory conducted an operational demonstration of the polarimetric utility of the Norman, Oklahoma (KOUN), Weather Surveillance Radar-1988 Doppler (WSR-88D). The capability of the KOUN radar to estimate rainfall is tested on a large dataset representing different seasons and different types of rain. A dense gaug...
