Abstract

In the present article, results of observations of high crystal clouds with high spatial and temporal resolution using the ground-based polarization LOSA-S lidar are described. Cases of occurrence of specularly reflective layers formed by particles oriented predominantly in the horizontal plane are demonstrated. Results of measuring echo-signal depolarization are compared for linear and circular polarization states of the initial laser beam.

摘要

在本文中，描述了使用地基偏振LOSA-S激光雷达对具有高空间和时间分辨率的高冰晶云进行观测的结果。展示了由主要在水平面上取向的粒子形成的镜面反射层的出现情况。比较了初始激光束的线偏振态和圆偏振态下回波信号去极化的测量结果。
