The article developed an ontology of the self-cleaning ability of the atmosphere from anthropogenic pollutants and identified the influence of significant factors on it. According to the website https://rp5.ru in the created database in the My SQL DBMS the average annual and average monthly values of meteorological indicators of accumulation of MPZA, MPZA2, MPZA3, and self-purification of the atmosphere PSA, UMPA were calculated and analyzed for the large industrial cities of Angarsk, Bratsk, Irkutsk with a high level of air pollution for 2010-2023. It has been shown that with a determination coefficient of 95.8-99.9%, instead of the MPZA3 indicator, the simpler MPZA2 indicator can be used, and instead of the difficult-to-calculate PSA indicator, the 1/MPZA indicator can be used. In Irkutsk in May, only in 7.1% of cases are favorable conditions for the dispersion of pollution formed in the atmosphere, while in Angarsk and Bratsk there are no favorable conditions for their dispersion.
