摘要

Backscatter and depolarization lidar measurements from clouds and precipitation are reported as functions of the elevation angle of the pointing lidar direction. The data were recorded by scanning the lidar beam (Nd: YAG) at a constant angular speed of ～3.5 deg s~-1 whole operating at a repetition rate of 10 Hz. The scan results Highlight known depolarization phenomena in clouds and precipitation, and contribute additional and often Essential information for the unambiguous characterization of their liquid, solid, or mixed phase. Moreover, in Rain and snow, there is an evident and at times spectacular dependence on the elevation angle.
