RISDifferential Reflectivity Calibration and Antenna Temperature
Publisher: American Meteorological Society
Abstract: AbstractTemporal differential reflectivity bias variations are investigated using the National Center for Atmospheric Research (NCAR) S-band dual-polarization Doppler radar (S-Pol). Using data from the Multi-Angle Snowflake ...
The Effects of Three-Body Scattering on Differential Reflectivity Signatures
Publisher: American Meteorological Society
Abstract: Effects of three-body scattering on reflectivity signatures at S and C bands can be seen on the back side of large reflectivity storm cores that contain hail. The fingerlike protrusions of elevated reflectivity have been ...
Studies of the Polarimetric Covariance Matrix. Part II: Modeling and Polarization Errors
Publisher: American Meteorological Society
Abstract: A polarimetric radar covariance matrix model is described to study the behavior of the co-to-cross covariances in precipitation. The 2 ? 2 propagation matrix with attenuation, differential attenuation, and differential ...
Weather Radar Ground Clutter. Part I: Identification, Modeling, and Simulation
Publisher: American Meteorological Society
Abstract: Real-time ground-clutter identification and subsequent filtering of clutter-contaminated data is addressed in this two-part paper. Part I focuses on the identification, modeling, and simulation of S-band ground-clutter ...
Weather Radar Ground Clutter. Part II: Real-Time Identification and Filtering
Publisher: American Meteorological Society
Abstract: The identification and mitigation of anomalous propagation (AP) and normal propagation (NP) ground clutter is an ongoing problem in radar meteorology. Scatter from ground-clutter targets routinely contaminates radar data ...
Modeling, Error Analysis, and Evaluation of Dual-Polarization Variables Obtained from Simultaneous Horizontal and Vertical Polarization Transmit Radar. Part I: Modeling and Antenna Errors
Publisher: American Meteorological Society
Abstract: In this two-part paper the biases of polarimetric variables from simultaneous horizontally and vertically transmitted (SHV) data are investigated. Here, in Part I, a radar-scattering model is developed and antenna polarization ...
Modeling, Error Analysis, and Evaluation of Dual-Polarization Variables Obtained from Simultaneous Horizontal and Vertical Polarization Transmit Radar. Part II: Experimental Data
Publisher: American Meteorological Society
Abstract: In this second article in a two-part work, the biases of weather radar polarimetric variables from simultaneous horizontally and vertically transmit (SHV) data are investigated. The biases are caused by cross coupling of ...
Studies of the Polarimetric Covariance Matrix. Part I: Calibration Methodology
Publisher: American Meteorological Society
Abstract: A procedure for calibration of the radar covariance matrix for the Colorado State University?University of Chicago?Illinois State Water Survey (CSU?CHILL) radar and S-Band Dual-Polarization Doppler Radar (S-Pol) systems ...
