Abstract

Lidar sounding of clouds give rise to multiple scattering contributions that contain useful information on cloud parameters. The challenge is to extract and make use of this information for the retrieval of the cloud droplet density and effective size. This paper is on the continuation of our group's effort for the development of a reliable inversion method of lidar returns measured at multiple fields of view. It is proposed to use the multiple scattering information to calibrate each lidar signal and derive from there the extinction coefficient at the lidar wavelength and the effective droplet diameter. The method is applied to two stratus cloud events. The solutions obtained are consistent with independent depolarization measurements and with general knowledge on cloud properties.
