Abstract

We have examined the characteristic of backscattering coefficient and depolarization ratio that are affected by multiple scattering in optically thick water clouds. We used observations obtained by the Multiple Field of view Multiple Scattering Polarization Lidar (MFMSPL) system. The MFMSPL was the first ground-based lidar that can detect depolarization ratio of optically thick clouds and it has 8 channels, i.e., 4 for parallel channels and another 4 for perpendicular ones and achieved total FOV of 70mrad. The MFMSPL offers a unique opportunity to simulate and study space-borne lidar signals including depolarization ratio such as from Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) lidar. It was shown that the attenuated backscattering coefficient and depolarization ratio constructed by using 8 channel observations by MFMSPL were comparable to the values obtained by CALIPSO lidar.
