Analysis of severe convective events from two operational dual polarisation doppler radars [PDF]
Natural Hazards and Earth System Sciences, 2006 The recent gradual increase in the use of polarimetric radars prompts for possible improvements in the estimation of precipitation and the identification of the prevailing hydrometeor type. An analysis of different convection episodes (20 May 2003, 4 and

A Semisupervised Robust Hydrometeor Classification Method for Dual-Polarization Radar Applications
Journal of Atmospheric and Oceanic Technology, 2015 AbstractMost of the recent hydrometeor classification schemes are based on fuzzy logic. When the input radar observations are noisy, the output classification could also be noisy, since the process is bin based and the information from neighboring radar cells is not considered.
