Experimental Determination of the Calibration Factor of Polarization-Mie Lidar

Abstract

Abstract:

A ground-based polarization-Mie lidar has been developed to measure backscattering signals from the atmosphere and linear depolarization ratios ? at 532 nm. To retrieve depolarization properties of clouds and aerosols, the calibration factor k of two polarization channels at 532 nm must be calculated. Three different experimental methods are presented to determine the calibration factor k in this polarization-Mie lidar. Some measured examples are presented and discussed. Experimental and validated results indicate these methods are feasible.

Key words: calibration factor, depolarization ratio, polarization-Mie lidar, CALIPSO
