Abstract

During the Convective and Orographically-induced Precipitation Study (COPS), lidar dark and bright bands were observed by the Univ. of BASILicata Raman lidar system (BASIL) on several IOPs and SOPs (among others, 23 July, 15 August, and 17 August). Dark/bright band signatures appear in the lidar measurements of the particle backscattering. Lidar data are supported by measurements from the University of Hamburg cloud radar MIRA 36 (36 GHz), the University of Hamburg dual-polarization micro rain radars (24.1 GHz) and the University of Manchester Radio UHF clear air wind profiler (1.29 GHz). Results from BASIL and the radars are illustrated and discussed to support in the comprehension of the microphysical and scattering processes responsible for the appearance of the lidar dark band and radar bright band. Simulations of the lidar dark and bright band based on the application of a concentric/eccentric sphere Lorentz-Mie codes and a melting layer model are also provided.
