Innovative Applications of Dual-polarization in Radar Meteorology, beyond the measurement of differential reflectivity and differential phase

Ever since the introduction of dual –polarization, for meteorological radars, this field has seen immense grown over the past three decades, to the point that dual-polarization radar has become a standard instrument for operational and research purposes. In addition to the measurement of differential reflectivity and differential phase, eventually the full matrix measurements were introduced. A combination of dual-polarization radar products such as, differential reflectivity ( Zdr ), specific differential phase ( Kdp ), and co-polar correlation coefficient ( hv ), in addition to reflectivity were used for hydrometeor classification. However since then the “fundamental nature of using dual-polarization “, has seen lot more applications beyond the basic process of rainfall estimation and hydrometeor classification. One such application is attenuation correction. This paper summarizes a series of significant applications involving polarization diversity that is beyond the original measurement of backscatter scattering matrix of precipitation.
