N2 - Polarimetric radar is capable of measuring a number of parameters such as reflectivity (Z), differential reflectivity (ZDR), Linear depolarization ratio (LDR), correlation between co-polarized signals and differential propagation phase shift (KDP). These multiparameter observations depend on size, shape and orientation and composition of precipitation particles in the radar sampling volume, for example, regions which contain mixture of rain and frozen hydrometeors(hail and graupel), and snow bands which consists of both pristine ice crystals and aggregates. Thus, there is a need to develop generalized polarimetric radar models to consider mixed phase precipitation and effects of larger elevation angles. Our multiparameter radar model is based on the averaged Mueller matrix where the averaging is performed over size, shape, orientation and composition of the different precipitation types. From the Mueller matrix elements, radar parameters such as 2, ZDR, LDR, KDP, etc., can be computed. The T-matrix method is used to compute the scattering amplitudes.
