The modeling is performed using ADMS Urban modeling system. In accordance with Article 6 of Directive 2008/50/EC of the European Parliament and of the Council, the modeling approach may supplement the fixed measurement approach or be used in zones and agglomerations where the pollution level is below the lower assessment threshold and provide adequate information on the spatial distribution of the ambient air quality.
