RISEfficient Atmospheric Simulation for High-Resolution Radar Imaging Applications
Publisher: American Meteorological Society
Abstract: Numerical simulation can be used for optimizing radar imaging techniques because it allows the accuracy of various techniques to be studied. A simulation of atmospheric conditions by using scatterers in a 3D volume was ...
Orientation Analysis of Simulated Tornadic Debris
Publisher: American Meteorological Society
Abstract: AbstractPolarimetric weather radars are capable of detecting tornadic debris signatures (TDSs), which result from debris being lofted to the level of the radar beam and can be modulated by centrifuging and debris fallout. ...
Observations of the Small-Scale Variability of Precipitation Using an Imaging Radar
Publisher: American Meteorological Society
Abstract: For many years, spatial and temporal inhomogeneities in precipitation fields have been studied using scanning radars, cloud radars, and disdrometers, for example. Each measurement technique has its own advantages and ...
A Dual-Polarization Radar Hydrometeor Classification Algorithm for Winter Precipitation
Publisher: American Meteorological Society
Abstract: he purpose of this study is to demonstrate the use of polarimetric observations in a radar-based winter hydrometeor classification algorithm. This is accomplished by deriving bulk electromagnetic scattering properties of ...
A Pulse Compression Waveform for Improved-Sensitivity Weather Radar Observations
Publisher: American Meteorological Society
Abstract: he progression of phased array weather observations, research, and planning over the past decade has led to significant advances in development efforts for future weather radar technologies. However, numerous challenges ...
High-Temporal Resolution Polarimetric X-Band Doppler Radar Observations of the 20 May 2013 Moore, Oklahoma, Tornado
Publisher: American Meteorological Society
Abstract: On 20 May 2013, the cities of Newcastle, Oklahoma City, and Moore, Oklahoma, were impacted by a long-track violent tornado that was rated as an EF5 on the enhanced Fujita scale by the National Weather Service. Despite a ...
A Novel Instrument for Real-Time Measurement of Attenuation of Weather Radar Radome Including Its Outer Surface. Part II: Applications
Publisher: American Meteorological Society
Abstract: AbstractThe concept and theory of a novel instrument to characterize the radio frequency performance of a radome under different conditions, including dirtiness, wetness, and varying temperature, was presented and discussed ...
A Novel Instrument for Real-Time Measurement of Attenuation of Weather Radar Radome Including Its Outer Surface. Part I: The Concept
Publisher: American Meteorological Society
Abstract: AbstractThis paper presents a unique instrument for characterizing the impact of wet radomes in radar systems. The proposed technique enables full radio frequency (RF) characterization of the radome, by evaluating its ...
Multilag Correlation Estimators for Polarimetric Radar Measurements in the Presence of Noise
Publisher: American Meteorological Society
Abstract: he quality of polarimetric radar data degrades as the signal-to-noise ratio (SNR) decreases. This substantially limits the usage of collected polarimetric radar data to high SNR regions. To improve data quality at low SNRs, ...
Observations of Severe Local Storms and Tornadoes with the Atmospheric Imaging Radar
Publisher: American Meteorological Society
Abstract: obile radar platforms designed for observation of severe local storms have consistently pushed the boundaries of spatial and temporal resolution in order to allow for detailed analysis of storm structure and evolution. ...
