Application of Information and Communication Technologies in Environmental Scientific Research (on Example of Sulfur Dioxide Emissions Research into the Atmospheric Air of Ukraine)

The research developed a geoinformation satellite monitoring technology for quantitative assessment of atmospheric air pollution over the territory of Ukraine. The technology is universal and allows for prompt monitoring of all greenhouse gases. This article is devoted to the complex geoinformation monitoring of sulfur dioxide. The research used data on the concentration of sulfur dioxide for 5 years: from 2019 to 2023 from the Sentinel-5P satellite product OFFL SO2 processing level L3. The Google Earth Engine (GEE) geospatial processing service was used to calculate and obtain remote sensing data. With the help of the ArcGIS geoinformation program, maps of SO2 distribution on the territory of Ukraine and adjacent territories were constructed. Regional areas with anomalous SO2 content values and transboundary SO2 transfer were identified. Using the comparison of satellite and ground measurements, a comparison graph was made between these observations, and 4 aggregates were selected. The integrated use of satellite and ground data allows for a significant increase in the informativeness of the proposed technology.
