The study used daily data on optical density of aerosols in the entire atmosphere based on measurements by the AURA satellite system with OMI (Ozone Monitoring Instrument) with a spatial resolution of 0.25° for the period from 2005 to 2025. Based on the processed images, a map of the average long-term values for the June–September season for the entire territory of the country was constructed. Long-term average, minimum and maximum values for each subject of the Russian Federation were calculated. The trends of aerosol optical density values were calculated and their statistical significance was determined. Trend analysis showed that an increase in the optical density of aerosol was observed in almost the entire territory of Russia in the period 2005–2025 according to the average data for the period from June to September. The climatic conditions of several southern regions of European Russia make it possible to analyze optical density of aerosol throughout the year. The annual course of aerosol optical density revealed that the maximum occurs in the period from April to July, and the minimum values are observed in November.
Keywords: aerosol optical density, satellite data, atmospheric pollution, subjects of the Russian Federation
