Abstract: In urban neighborhood and around industrial plants, the atmospheric dispersion of pollutants is strongly affected by the presence of buildings. They affect the mean flow field and the turbulence and these in turn will affect the concentrations levels. We describe the use of Computational Fluid Dynamics models (adapted for the atmosphere), following either an Eulerian/Eulerian approach or an hybrid Eulerian/Lagrangian formulation. The results are illustrated using measurements of the Mock Urban Setting Test (MUST) campaign performed in the USA. Using the same field campaign, we will also show how we can use data assimilation of the measurements between the buildings to improve the numerical simulation in urban environments.
