How do ice crystal habits and size distribution characteristics affect 95 GHz radar signals?
PAPER WITHDRAWN Henriette M. Lemke, GKSS Research Center, Geesthacht, Germany; and M. Quante The potential of ground-based polarimetric and Doppler cloud radar measurements to improve information about ice cloud microphysics is evaluated. Using the discrete dipole approximation (DDA), backscattering at 95 GHz (3.16 mm) has been computed for various ice crystal shapes. Crystal sizes up to 2 mm in maximum dimension in various orientation scenarios have been modelled. Different size distribution types have been considered representing the same fixed ice water content. Based on the modelling results, the effect of ice crystal habits and size distribution characteristics on radar observables as co-polar reflectivity (Zhh), linear depolarization ratio (LDR), and differential reflectivity (ZDR) as well as difference reflectivity (ZDP) can be investigated. Technical radar aspects such as scanning capability and cross polarization isolation requirements are assessed. For the polarimetric radar
