Original abstract
In the paper authors describe two-scale PM dispersion modeling in an urban area. CFD code StarCD was used to build up two models of the urban area. Combination of the regional model and the local scale model is used for the correct description of dispersion processes. The regional solution domain represents an area 12 x12 km. The local solution domain represents an area of approximately 1 x1 km. Traffic is considered as the primary source of airborne particles. The paper focuses on the modeling of deposition process of PM in an urban area and an accompanying process of re-suspension of once deposited particles that are lifted by traffic and dispersed into surroundings. Concentrations of PM10 are modeled and compared with results of measurements carried out in several locations of the solution domain.
