Abstract :
The intensification of air pollution under the influence of various factors, including population growth and urbanization, is the concern of activists in this field. It is necessary to check the pollutants carefully using precise techniques. In this study, elements of NO2, CO, and Particulate Matter effective in air pollution were analyzed spatially and temporally (monthly, annually) using the TROPOMI instrument of Sentinel 5 sensor in East Azerbaijan province. Investigations showed that in the cold season, more areas of the region experience the presence of CO and NO2 pollutants, which are mainly caused by fossil fuels, industries, and residential areas. But their concentration is high in the hot and cold seasons respectively. Evidence shows that in densely populated areas, we are facing high concentrations and the presence of NO2. A high concentration of suspended particles is also seen in the summer season. According to the findings, all three elements have a high distribution in the cold season; on the other hand, the concentration and spatial distribution of pollutants is influenced by factors such as weather, topographical conditions, and industrial centers.
