The seasonal and interannual variations of sulfur dioxide content in the troposphere column were estimated from measurements of the OMI (Ozone Monitoring Instrument) instrument of the Aura satellite with a spatial resolution (SR) of 0.25×0.25° for the period 2005–2024 using the Giovanni system, and the assessment of anthropogenic SO2 emissions based on the CAMS-GLOB-ANT v5.3 inventory of the ECCAD (Emissions of atmospheric Compounds and Compilation of Ancillary Data) online service available for grids with SR of 0.1×0.1° for the period 2000–2023, using the example of several Russian cities. The choice of the territories (Norilsk, Reftinsky, Karabash, Chelyabinsk, Donetsk, and Lugansk) is based on the increased anthropogenic emissions of SO2 according to the CAMS-GLOB-ANT inventory data and satellite data. A comparison was made between the inventory data on sulfur dioxide emissions and the satellite data on SO2 content in the atmospheric column. Both the inventory data and the satellite data show a decrease in emissions and SO2 content in the atmosphere during the summer season. In some cases, the satellite estimates of emissions do not agree with the inventory data.
