Abstract :
In this paper, application of white light lidar system for the multi-wavelength depolarization measurement of clouds and aerosols will be presented. The new lidar system consisted of three depolarization channels at 450, 550 and 800 nm. The linear depolarization ratio (delta = S/P) at 450 nm can be seen to increase with increasing cloud depth due to the multiple scattering.
