A new obstacle resolving atmospheric micro-scale chemistry, transportand flow model MITRAS has been developed within the TroposphericResearch Program (TFS). MITRAS is an obstacle resolving model solvingsimultaneously the chemistry, pollutant transport including soot as well asflow and temperature field. The chemical reaction module is based on asimplified RACM mechanism. MITRAS has been carefully tested againstquality ensured wind tunnel data. The model results on soot and ozoneconcentrations as well as on the spatial representativity of measurementsites underline the necessity for high-resolution flow simulationsincluding temperature effects for case studies on close-to-sourcechemistry and pollutant transport within the urban canopy.
