Polarimetric Radar Observation Operator for a Cloud Model with Spectral Microphysics

Polarimetric Radar Signatures of a Simulated Supercell Storm Using a Two-Moment Microphysics Scheme and Polarimetric Radar Emulator

i Abstract A general polarimetric radar emulator is developed based on rigorous scattering calculations using the T-matrix method for reflectivity, differential reflectivity, specific differential phase, and co-polar cross-correlation coefficient. A continuous melting process accounts for the entire spectrum of varying density and dielectric constants. This emulator is able to simulate polarime...

An intercomparison of radar-based liquid cloud microphysics retrievals and implications for model evaluation studies

This paper presents a statistical comparison of three cloud retrieval products of the Atmospheric Radiation Measurement (ARM) program at the Southern Great Plains (SGP) site from 1998 to 2006: MICROBASE, University of Utah (UU), and University of North Dakota (UND) products. The probability density functions of the various cloud liquid water content (LWC) retrievals appear to be consistent with...

Cloud Microphysics Retrieval Using S-Band Dual-Polarization Radar Measurements

The recent deployment of multiparameter, polarimetric radars provides the impetus for development of microphysical retrievals. The primary objective of this paper is to describe a particle classification technique that makes use of polarimetric radar observations. The particle classification technique is computationally simple enough to be implemented for real-time research and operational fiel...

Simulations of Polarimetric Radar Signatures of a Supercell Storm Using a Two-Moment Bulk Microphysics Scheme

A new general polarimetric radar simulator for nonhydrostatic numerical weather prediction (NWP) models has been developed based on rigorous scattering calculations using the T-matrix method for reflectivity, differential reflectivity, specific differential phase, and copolar cross-correlation coefficient. A continuous melting process accounts for the entire spectrum of varying density and diel...
