heal.abstract	A three-dimensional Eulerian transport model is presented for the mesoscale simulation of pollutant dispersion and photochemistry in complex terrain. Equations describing SO2 chemistry are also added to the chemical mechanism, which is solved by the QSSA technique. The differential equations of the wind field, expressed in Cartesian co-ordinates, are discretised by the finite volume method and solved iteratively with the SIMPLE algorithm. Advanced techniques, as local grid refinement and partially blocked cells are used for a better representation of the complex terrain, as also a higher order scheme for the discretisation of the convection terms. The complete model was applied for the case of Athens, Greece, during a pollution episode which happened on the 25th of May 1990. The results reproduce reasonably well the diurnal variation of NOx, O3 CO, and SO2 species concentration. The comparison between predictions and available measurements taken at several surface measuring stations is satisfactory.A three-dimensional Eulerian transport model is presented for the mesoscale simulation of pollutant dispersion and photochemistry in complex terrain.
