Abstract
An analysis is made of the development of lidar and searchlight methods of atmospheric research carried out in recent years at the Institute of Atmospheric Optics. A description is given of using the temperature dependence of the intensity ratio of the optimal combination of temperature-sensitive lines of the rotational Raman spectrum on nitrogen and oxygen molecules for the lidar determination of temperature profiles. The application of the method of differential absorption and scattering to estimate the content of gas impurities in the UV and near and middle IR ranges is described. The possibility of placing a differential absorption lidar on a space platform to determine the total content of methane and carbon dioxide in the atmosphere is analyzed. The conditions for the detection of polar and silvery clouds in the atmosphere above Tomsk are studied. The lidar-optical characteristics of cirrus clouds consisting of ice crystal aggregates are also determined. The use of postfilation beams for wide-spectrum sensing of an aerosol atmosphere has been founded. The results of searchlight sensing of atmospheric formations that create the phenomenon of mirror reflection are given.
