The study has main objective to predict the air quality in populated areas with respect to prevailing wind direction. Simultaneous point measurement of two velocity components and concentrations by Laser Doppler Anemometry (LDA) and Fast Flame Ionization Detector (FFID), respectively, was performed during wind-tunnel experiment. The velocity and concentration field obtained from wind-tunnel measurements are compared with those from LES. The impact of complex topography and especially surface roughness on passive pollutant dispersion was observed. The comparison revealed that LES has a big potential to predict atmospheric dispersion processes occurred at complex terrain topography.
