Cloud Microphysics Retrieval Using S-Band Dual-Polarization Radar Measurements

Jothiram Vivekanandan, +5 more
- 01 Mar 1999 - 
TL;DR: This preliminary study has developed and implemented a fuzzy logic algorithm for hydrometeor particle identification that is simple and efficient enough to run in real time for operational use.
Journal ArticleDOI

Experiments in Rainfall Estimation with a Polarimetric Radar in a Subtropical Environment

Edward A. Brandes, +2 more
- 01 Jun 2002 - 
TL;DR: In this paper, a unique dataset consisting of high-resolution polarimetric radar measurements and dense rain gauge and disdrometer observations collected in east-central Florida during the summer of 1998 was examined.
Journal ArticleDOI

A method for estimating rain rate and drop size distribution from polarimetric radar measurements

Guifu Zhang, +2 more
- 01 Apr 2001 - 
TL;DR: The authors propose and demonstrate a method for retrieving DSD parameters for calculating rain rate and the characteristic particle size and shows improvement over the existing models and techniques because it can retrieve all three parameters of the gamma distribution.
Journal ArticleDOI

The Shape–Slope Relation in Observed Gamma Raindrop Size Distributions: Statistical Error or Useful Information?

Guifu Zhang, +4 more
- 01 Aug 2003 - 
TL;DR: In this article, the error propagation from moment estimators to rain DSD parameter estimators is studied, and the standard errors and correlation coefficient are derived through systematic error analysis using numerical simulations, and errors in estimated DSD parameters are quantified.
Journal ArticleDOI

Boundary Layer Clear-Air Radar Echoes: Origin of Echoes and Accuracy of Derived Winds

James W. Wilson, +4 more
- 01 Oct 1994 - 
TL;DR: In this paper, the authors used dual-wavelength and dual-polarization radars to examine the cause of these echoes and the use of Doppler velocities from the clear-air return to estimate winds.
