Ground-based Stationary Differential Absorption Lidars for Monitoring Greenhouse Gases in the Atmosphere
Natural and anthropogenic increase in the greenhouse gas concentrations in the atmosphere is currently considered a determining factor in climate change and global warming. In this regard, there is an urgent need for the development of new techniques for remote monitoring of greenhouse gases with high spatiotemporal resolution and accuracy. Remote laser (lidar) systems enable more accurate and of higher information content measurements of atmospheric concentrations of greenhouse gases in comparison with standard contact gas analysis methods. The characteristics and description of differential lidars for monitoring methane, carbon dioxide, water vapor, ozone, and other gas components are given. The results of the development of ground-based stationary differential absorption lidar systems for remote monitoring of key greenhouse gases in the atmosphere in the past 25 years are systematized and analyzed. This review can be useful for specialists who design systems for remote gas analysis of the atmosphere.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
