Abstract

The paper presents the results of numerical simulation of the signal of a scanning lidar probing cirrus clouds. Two types of clouds were studied: clouds consisting of randomly oriented particles of arbitrary shape and predominantly oriented hexagonal columns, and clouds consisting of randomly oriented particles of arbitrary shape and predominantly oriented hexagonal plates. The obtained results show good agreement between the calculated data and the results of experimental observations on the scanning lidar of the V.E. Zuev Institute of Atmospheric Optics of Siberian Branch of the Russian Academy of Sciences. The capability of a scanning lidar to determine the flutter angle of oriented particles based on the analysis of the lidar signal intensity and the depolarization ratio is demonstrated.
