THE DISTRIBUTION OF SO-2, NO-2 AND OZONE CONCENTRATIONS AND THE RESULTS OF A NUMERICAL SIMULATION
During the TULLA field campaign measurements of concentrations of SO-2, NO, NO-2, O-3 and some other species have been carried out in the lower troposphere and at the ground to study the distribution of air pollutants in a mesoscale region. On the base of these measurements it is possible to consider the time variations of concentrations as a function of variable source strength, variable meteorological conditions and chemical reaction rate in the atmosphere. Also vertical profiles may be analyzed at several points. Examples of numerical simulations of atmospheric flow conditions over irregular terrain of the state Baden-Wuerttemberg will be discussed according to the present status of the model developments. Special emphasis will be given to the influences of the terrain on the flow modifications in the lower atmosphere. Some simulations include the calculation of the turbulent transport and the diffusion of air pollutants over the mesoscale TULLA area emitted from intensive point sources. Some qualitative comparisons between measurements and modelling results are added.
