Determination of suspended aerosols in the atmospheric air according to the dust analyzer Atmas on the example of the Sevastopol City

Abstract

The paper presents the results of the mass concentration of PM2.5 and PM10 particles measurements which were carried out using the Atmas dust analyzer (manufactured in Russia) for 2021. The analysis of the results showed that the period with the maximum values of the mass concentration of suspended particles PM10 and PM2.5 was observed in November-December of the year under study. Also, throughout the year the dates with an excess of the average monthly concentrations by more than 2 times were identified and an analysis of atmospheric pollution by suspended PM particles was carried out for them using the SILAM model. The results of modeling the back trajectories of air flow movement performed using the HYSPLIT software package were used to determine the source of PM10 and PM2.5 particle transport.
