Analysis of Mixing Ratios of Greenhouse Carbon-Containing Gases at the Atmospheric Monitoring Station of St. Petersburg State University
In order to study temporal variations in the mixing ratios of greenhouse carbon-containing gases and factors influencing them, local measurements of CO2, CH4 (January 2013–January 2020), and CO (January 2013–January 2019) mixing ratios in atmospheric air at the monitoring station of St. Petersburg State University are analyzed taking into account trends and seasonal fluctuations. Linear trends for CO2, CH4, and CO, which are 2.42 ppm/year (0.60%), 8.6 ppb/year (0.49%), and −3.8 ppb/year (−2.2%), respectively, are in a good agreement with independent estimates of both global/background changes and changes in urban areas. The analysis of the CO/CO2 emission ratio confirmed that motor vehicles are the dominant anthropogenic source affecting the composition of atmospheric air near the monitoring station of St. Petersburg State University. The results can be used for validation of atmospheric models and independent estimation of greenhouse gas fluxes.
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.
