Abstract:
The paper presents results from aerosol experimental campaigns performed in the urban environment of Sofia. Laser Particle Counter (PLC) data of 2 summer days (June, 7 and 8) and 4 winter days (December, 18, 19, 20, 21) of 2019 are discussed. Aerosol particle concentrations (number/l and mass μg/m3) in channels 0-2.5 μm and 2.5-10 μm are measured at the open green area near Pliska (at 30 m distance from boulevard Tsarigradsko shose). The combined effect of the daily development of atmospheric boundary layer height, meteorological parameters, and hourly variations in the concentrations of the aerosol fractions is discussed. WRF-GDAS and HYSPLIT models are used for determination of the atmospheric boundary layer height and to follow the transport of air masses. BSC-DREAM dust model is used as an additional source of information to assess the long-range intrusion of dust.
