Abstract
Results of a series of spectroscopic measurements of the tropospheric NO2 content carried out on a closed route of the Ring Road of St. Petersburg in different seasons in 2012, 2014, 2015, and 2016 are considered. A unified approach to the interpretation of all experimental data using numerical modeling of air pollution spread and a priori information about the spatial distribution of its anthropogenic sources has significantly improved the accuracy of determining the integral NOx emissions. The total NOx volume, reduced to gross annual anthropogenic emissions from the territory of St. Petersburg, amounted to 81 000 ± 17 000 t. This value slightly exceeds the air pollution city inventory official data (from 61 000 to 63 000 t per year), consistent within the error margin with the estimate obtained earlier on the basis of similar mobile measurements in the spring of 2019 (75 000 ± 26 000 t per year).
期刊介绍：
Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
