The possible temperature influence on the microparticle concentration in the near-surface layer of the Earth is presented. As input data we used either temperature variation instrumental observations as well as less than 2.5 μm (PM2.5) microparticle mass concentrations in the subsurface layer of the atmosphere. The measurements were held during the summer period of 2021 and 2022 years in the midlatitude Mikhnevo Geophysical Observatory of IDG RAS. While data processing and analysis, a strong correlation between the daily mean temperature values and PM2.5 concentrations was established. The maximum value of the Pearson linear correlation coefficient between the considered values was obtained in July. A high correlation is observed both for individual monthly correlations and for summer periods in general.
