Simultaneous Transmission Mode for the Polarimetric Wsr-88d Statistical Biases and Standard Deviations of Polarimetric Variables

Erad 2014 - the Eighth European Conference on Radar in Meteorology and Hydrology

The United States’ Next Generation Weather Radar (NEXRAD) program has deployed a polarimetric upgrade to the WSR-88D network radars. This modification provides new base variables to the operational community and has opened exciting new possibilities for improved forecasts and warnings. One variable in particular, differential reflectivity (ZDR), is critically important to improved precipitation...

Principles and Applications of Dual-Polarization Weather Radar. Part I: Description of the Polarimetric Radar Variables

The United States Weather Surveillance Radar-1988 Doppler (WSR-88D) radar network has been upgraded to dual-polarization capabilities, providing operational and research meteorologists with a wealth of new information regarding the types and distributions of hydrometeors within precipitating storms, as well as a means for improved radar data quality. In addition to the conventional moments of r...

Rainfall Measurements with the Polarimetric WSR-88D Radar

4r.5 Demonstration of Range Oversampling Techniques on the Wsr-88d

Among the planned upgrades for the NEXRAD network of weather surveillance radars are superresolution (1/4 km reflectivity and 0.5 deg radials) and polarimetric capabilities. In either case, keeping current update times (i.e., same antenna rotation rates) results in meteorological variable estimators with unacceptable large errors. A family of methods to reduce errors in estimates of spectral mo...
