The neutrally stratified atmospheric dispersion over real complex terrain – open-cut coal mine with necessary surroundings – was simulated in order to predict the air quality in populated areas situated close to the coal mine with respect to prevailing wind direction. As a computational model the LES numerical model Charles University Large-eddy Microscale Model (CLMM) was used. The mean velocity and concentration field obtained from wind-tunnel measurements are compared qualitatively with those from LES by means of Hit Rate and FAC2 (Factor of two observations) metric, respectively. According to metrics thresholds and recommended metric parameters the LES model was successfully validated with respect to dimensionless longitudinal velocity component and concentration.
