The mobile aerosol Raman polarizing lidar LOSA-A2 designed at V.E. Zuev Institute of Atmospheric Optics SB RAS is presented. Its main technical specifications are given. The lidar carries out sounding of the atmosphere of a Nd:YAG laser at two wavelengths, 1064 nm and 532 nm. Optical selection of lidar signals at these wavelengths is performed by two identical telescopes with diameters of 120 mm and a focal length of 500 mm. In the visible channel, the signal is divided into two orthogonal polarized components, and a Raman signal at a wavelength of 607 nm is separated. The lidar was tested in aircraft and ship research expeditions. Results of the study of spatial aerosol distribution over the Baikal with the use of LOSA-A2 lidar received during ship-based research expeditions are described. The first in situ tests of the lidar were carried out in an aircraft expedition in the north of Western Siberia.

移动式气溶胶拉曼偏振激光雷达LOSA-A2，用于大气探测

介绍了由VE Zuev大气光学研究所SB RAS设计的移动式拉曼偏振激光雷达LOSA-A2。给出了其主要技术规格。激光雷达对Nd：YAG激光的大气发出1064 nm和532 nm两种波长的声音。通过两个直径为120 mm，焦距为500 mm的相同望远镜对这些波长的激光雷达信号进行光学选择。在可见通道中，信号被分成两个正交的偏振分量，并且分离了607 nm波长的拉曼信号。激光雷达已在飞机和舰船研究考察中进行了测试。描述了在基于船的研究远征中使用LOSA-A2激光雷达对贝加尔湖上的空间气溶胶分布进行研究的结果。
