Recent advances in classification of observations from dual polarization weather radars
It has been a decade since some of the early papers on dual-polarization radar based hydrometeor classification were published. Subsequently this topic has seen rapid advances especially due to adaptation of this technology for operational applications. Since the early papers on hydrometeor classification, additional characterization in terms of echo classification, data quality and hydrometeor identification have been researched, and products produced some distinctly, some with all three procedures combined. This paper provides a summary of the advances since the early papers in this area, especially with an emphasis on how the successful operational applications have influenced this field. Principles of the various types of classification and examples of characterizations such as data quality, echo and hydrometeor classification are also described. âº Precipitation classification methods from Dual-polarization radar observations. âº Precipitation echo classifier from Dual-polarization radar measurements. âº Precipitation classification examples from S, C and X band radar observations. âº Summer and winter precipitation classification from weather radar. âº Review of various precipitation and echo classification systems from weather radar.
