- 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).
