In this work application of dual polarization spectral analysis for retrieval of microphysical properties of ice particles is presented. In the presented examples retrievals of drop size distribution parameters for two types of particles that are present in the radar volume are shown. The selection of the types of ice particles that are considered for retrievals is done based on both meteorological conditions and radar scattering properties.
The presented work is illustrated by the retrievals of drop size distribution parameters of plates and snow aggregates observed above a melting layer of stratiform precipitation. The spectral reflectivity and spectral differential reflectivity are simulated for a combination of plates and aggregates with realistic statistical properties. Based on these simulations a retrieval technique is obtained which provides the micro physical properties of plates and aggregates. It is shown that under certain assumptions the parameters of the drop size distribution can be retrieved for both types of particles.
