TLDR
The polarization properties of lidar backscattering from the atmosphere have been measured using a ruby system operating at 694.3 nm and 347.2 nm to find that the polarization of the scattered signal varies substantially with meteorological conditions and that the signals can be employed to derive useful information about the atmospheric conditions.Abstract:
The polarization properties of lidar backscattering from the atmosphere have been measured using a ruby system operating at 694.3 nm and 347.2 nm. Linearly polarized signals are transmitted, and multiple receiver channels simultaneously sample the return with polarizers oriented parallel and perpendicular to the transmitted polarization. It is found that the polarization of the scattered signal varies substantially with meteorological conditions and that the signals can be employed to derive useful information about the atmospheric conditions.read more

TL;DR: In this paper, the vertical profiles of the linear particle depolarization ratio of pure dust clouds were measured during the Saharan Mineral Dust Experiment (SAMUM) at Ouarzazate, Morocco, close to source regions in May-June 2006, with four lidar systems at four wavelengths (355, 532, 710 and 1064 nm).

Potential of polarization/Raman lidar to separate fine dust, coarse dust, maritime, and anthropogenic aerosol profiles
TL;DR: In this article, the authors applied the recently introduced polarization lidar-photometer networking (POLIPHON) technique for the first time to triple-wavelength polarization LIDAR measurements at 355, 532, and 1064 nm.
