“…The greatest increase in the studied aerosol characteristics was recorded on February 4, 2018 (σ d = 1078 Mm -1 and eBC = 31 µg/m 3 ). A temperature-wind complex operates in monitoring mode in Akademgorodok since 2015, which includes, among other instruments, a temperature profiler MTR-5 [12][13] , which determines temperature in the boundary layer of the atmosphere, as well as an ultrasonic weather station "Meteo-2", which measures air temperature, wind speed and direction at an altitude of 17m from the underlying surface. Using the data on the temperature profile, the vertical profile of the absolute temperature gradient was calculated, equal to the temperature difference at neighboring levels with a step of 50m, normalized to this step.…”
