Abstract
The intense urbanization observed in the world is accompanied by the active growth of urban agglomerations. The largest Moscow agglomeration in Europe is currently dynamically developing, which leads to the emergence of additional factors contributing to changes in urban ecosystems, weather and climate. One of the indicators of such processes is the variability of the properties of atmospheric aerosols. In this study, the main types of natural and anthropogenic impacts and their characteristic features are identified. To this end, a comprehensive algorithm for assessing the indicators of typical aerosol pollution of the city atmosphere and classifying impacts has been developed based on the results of continuous six-year (2020-2025) experimental observations at IAP RAS and measurements from the Mosecomonitoring network. The results can be used to clarify the aerosol emissions in Moscow, in chemical transport models, and in assessing and forecasting the state of urban ecosystems and climate.
