| Zusammenfassung |
| Multi-wavelength lidar measurements in the melting layer revealing the
presence of dark and bright bands have been performed by the University of
BASILicata Raman lidar system (BASIL) during a stratiform rain
event. Simultaneously radar measurements have been also performed from the
same site by the University of Hamburg cloud radar MIRA 36
(35.5 GHz), the University of Hamburg dual-polarization micro rain radar
(24.15 GHz) and the University of Manchester UHF wind profiler (1.29 GHz).
Measurements from BASIL and the radars are illustrated and discussed
in this paper for a specific case study on 23 July 2007 during the Convective
and Orographically-induced Precipitation Study (COPS). Simulations of the
lidar dark and bright band based on the application of concentric/eccentric
sphere Lorentz-Mie codes and a melting layer model are also provided. Lidar
and radar measurements and model results are also compared with measurements
from a disdrometer on ground and a two-dimensional cloud (2DC) probe on-board
the ATR42 SAFIRE. Measurements and model results are found to confirm and
support the conceptual microphysical/scattering model elaborated by Sassen et
al. (2005). |
