Evaluation and application of hydrometeor classification algorithm outputs inferred from multi‐frequency dual‐polarimetric radar observations collected during HyMeX

open access: yesQuarterly Journal of the Royal Meteorological Society, 2015
A fuzzy logic hydrometeor classification algorithm (HCA), allowing discrimination between six microphysical species regardless of the radar wavelength is presented and evaluated. The proposed method is based upon combination sets of dual‐polarimetric observables (reflectivity at horizontal polarization ZH, differential reflectivity ZDR, specific ...

Hydrometeor Classification for Dual Polarization Radar Based on Multi-Sample Fusion SVM [PDF]

open access: yesRadioengineering, 2023
In order to enhance the accuracy of dual polarization radar in hydrometeor classification, a hydrometeor classification algorithm based on multi-sample fusion Support Vector Machine (SVM) is proposed in this paper after considering that traditional fuzzy

Development of a polarimetric radar based hydrometeor classification algorithm for winter precipitation [PDF]

open access: yes, 2012
The nation-wide WSR-88D radar network is currently being upgraded for dual-polarized technology. While many convective, warm-season fuzzy-logic hydrometeor classification algorithms based on this new suite of radar variables and temperature have been refined, less progress has been made thus far in developing hydrometeor classification algorithms for ...

The NSSL Hydrometeor Classification Algorithm in Winter Surface Precipitation: Evaluation and Future Development

open access: yesWeather and Forecasting, 2011
Abstract The National Severe Storms Laboratory (NSSL) has developed a hydrometeor classification algorithm (HCA) for use with the polarimetric upgrade of the current Weather Surveillance Radar-1988 Doppler (WSR-88D) network. The algorithm was developed specifically for warm-season convection, but it will run regardless of season, and so ...
