Abstract
We presented a study of orography and meteorological regime influence on the transfer and accumulation of PM2.5 and PM10 in urban conditions over the foothill area in Kislovodsk (43.9194N, 42.7235E). It is an important recreational city at the south of Russia in the foothills of the Caucasus mountains. The vertical PM2.5 and PM10 concentrations of 0–500 m height were investigated using a multirotor unmanned aerial vehicle (drone). The measurements were carried out from January 26 to February 2, 2023, at 5 points: one outside the city at 1300 m altitude (43.8433N, 42.6949E) and 4 urbans points. The measurement data were compared with MAIAC/MODIS, SCIAMACHY data and the results of COSMO-ART chemical transport model calculations using CAMS data for initial anthropogenic emission estimates. The diurnal variations of emissions was adjusted according to long-term measurements of Kislovodsk. To assess the orography impact, we have carried out a calculation with a flat orography. The estimates of radiation and temperature effects of vertical PM2.5/PM10 profiles with different synoptic conditions are also shown.The work was supported by the Ministry of Education and Science of the Russian Federation (# 075-15-2021-574).
