Abstract

The subject of research was the vertical distribution of the concentration of solid particles during temperature inversions. The measurements were carried out using attachments mounted on the Unmanned Aerial Vehicle, including sensors for meteorological parameters and particulate matter. The flights were carried out during daylight hours in the absence of clouds at altitudes up to 500 m. It was found that in the presence of temperature inversion, the concentration of PM2.5 aerosol particles decreases with height and positively correlates with relative humidity. These patterns are violated when the atmosphere is polluted with the smoke of a city fire (the ignition area is about 12,500 m²).
