The possibility of conducting a study of atmospheric pollution in Ukraine with nitrogen dioxide, sulfur dioxide, carbon monoxide, and methane using data collected by Sentinel 5P satellite with the TROPOMI tool and the Google Earth Engine platform in the period from 2019 to 2023 years was considered. Developed a methodology for analyzing air quality for quick research of the dynamics of changes in pollutant concentrations based on satellite data. Thematic maps of the amount of pollutants across the territory of Ukraine, Kendall trend maps, and graphs of average gas concentrations by month for the selected period of 5 years were constructed. The results obtained for each of the studied gases were analyzed, revealed the regularity of seasonal changes and the impact of events of recent years, covering the quarantine period due to the COVID-19 pandemic and the beginning of a full-scale invasion of Russia. An assessment of the possibility of using remote monitoring in state environmental protection programs, for example, the European Clean Air for Europe (CAFE) program, was conducted. An attempt was made to compare the amount of the studied gases recorded by the satellite with the maximum permissible standards of Ukraine, but the results turned out to be implausible due to different units of measurement, the complexity of the conversion, and the need to involve a large amount of additional data.
