Comparison of different dispersion modelling approaches in the surroundings of Legerova street canyon in the city of Prague
Original language description
The dispersion of particulate matter (PM10) was studied in the vicinity of one of the main boulevards connecting the north and south of Prague, Czech Republic. A wintertime episode characterized by a strong temperature inversion was selected to perform the intercomparison of three models with varying degree of complexity: the Gaussian dispersion model ATEM, the Graz Lagrangian model (GRAL), and the Large-eddy simulation model PALM. Results highlight the importance of implementing a thorough validation of the models including a temporal and spatial analysis of the outputs. While statistical metrics indicated that ATEM could reasonably predict measurements in the domain, further examination led to conclude that relevant information on the dispersion of pollutants along street canyons was overlooked. GRAL, on the other hand, provided a better representation of circulation patterns in built-up areas, but generally overpredicted concentrations. Although PALM offered the most accurate results, high-resolution input data and high computational costs may limit the practical application of the model. © 2024 22nd International Conference on Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes, HARMO 2024.
