Abstract—

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.
