A Mie backscattering model for spherical particles with off-center inclusion has been developed and tested. The program is capable to deal with size parameter values up to ~1000, thus allowing to simulate the optical behaviour of a large variety of atmospheric aerosols, as well as cloud and precipitation particles. Based on this model, we simulated the optical properties of polydisperse composite atmospheric particles observed both by ground-based and air-borne lidar systems. Optical properties have been characterized in terms of host and inclusion radii, considering water particles with different composition inclusions. The performed modelling provides some insight into the so-called lidar bright and dark band phenomenon.

Abstract
A Mie backscattering model for spherical particles with off-center inclusion has been developed and tested. The program is capable to deal with size parameter values up to ~1000, thus allowing to simulate the optical behaviour of a large variety of atmospheric aerosols, as well as cloud and precipitation particles. Based on this model, we simulated the optical properties of polydisperse composite atmospheric particles observed both by ground-based and air-borne lidar systems. Optical properties have been characterized in terms of host and inclusion radii, considering water particles with different composition inclusions. The performed modelling provides some insight into the so-called lidar bright and dark band phenomenon.| File | Dimensione | Formato | |
