Abstract: We examine the utility of the correlation coefficient between linear orthogonally polarized echoes for determining precipitation type and gauging hail size. Models and measurements from pure rain coincide in predicting ...

Abstract: This paper presents an analysis of the accuracy of rain rate estimates from data observed with a radar that has alternating horizontal and vertical polarization. Theoretical accuracies of rain rates from the reflectivity, ...

Abstract: Processing of simultaneous measurements of differential polarization parameters (differential reflectivity, ZDR, and differential phase shift, ?DP) and Doppler spectral moments is discussed. It is shown how ZDR and ?DP ...

Abstract: The reflectivity factor (Z), rainfall rate (R) relationship for weather radars that probe precipitation at low elevation angles is sensitive to polarization. It is shown how to transform a relation that is valid with one ...

Abstract: The NSSL Doppler radar has been upgraded to include polarimetric measurements and remote operations. We discuss details of thew upgrades and specifics concerning real-time computations of polarimetric variables. Tests and ...

Abstract: In this paper, a new algorithm for the estimation of spectral parameters from the signal time series, collected using the staggered pulse repetition time (PRT) transmission in a Doppler weather radar, is presented. The ...

Abstract: In the staggered pulse repetition time (PRT) radar, the phase difference between the autocorrelations at lag T1 and T2 is used for velocity estimation. This paper investigates velocity estimates from the autocorrelation ...

Abstract: The following advantages of rain measurements using specific differential phase are examined: 1) immunity to beam blockage, 2) immunity to ground clutter canceling, and 3) case to isolate effects of anomalous propagation. ...

Abstract: On 9 June 1993, a squall line passed over the National Severe Storms Laboratory Cimarron radar and polarimetric data of this event were recorded. The line produced heavy rain and at one time was oriented north-south, ...

Abstract: In this paper a method is presented for separating overlaid echoes in a Doppler weather radar that uses a staggered pulse repetition time (PRT) transmission scheme to mitigate the effects of range?velocity ambiguities. In ...
