Lidar complex at small station of high-altitude atmospheric sensing in Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences makes it possible to obtain promptly and regularly the profiles of the scattering ratio up to the altitude of 70 km and atmospheric temperature and density in the altitude range of 10-70 km with the spatial resolution of 192 m. We developed a schematic optical diagram and design documentation for a six-channel receiving unit for receiving signals at the wavelengths of 532, 607, 355, and 384 nm, and wrote an algorithm for controlling and recording the signals in eight-channel photon counter.
Determining the aerosol microphysical properties is an important scientific and applied problem. In practice, most often the interpretation of lidar data is based on the laser sensing equation, which is valid for media with a small optical thickness. During sensing of optically dense formations, it is necessary to take into account the contribution of multiple scattering to the lidar return. In addition to significant attenuation, multiple scattering leads to the depolarization of radiation. The purpose of the present report is to discuss the effect of the polarization state of sensing radiation on its extinction in water-milk suspension.
