HIGH VERTICAL RESOLUTION NUMERICAL SIMULATION OF SUMMER FLOWS IN CATALONIA. IMPLICATIONS TO SPATIAL AND TEMPORAL VARIABILITY OF OZONE AND PM10 LEVELS

The aim of this study is to analyze the dynamics of the sea-breeze and its effects on the 3D pollution transport using ground based monitoring station, Sodar measurements and numerical simulation. We use the non-hydrostatic atmospheric model MM5 coupled to the photochemical model CMAQ. Measurements are basically focused on the determination of the propagation of the sea breeze front inland and on the validation of the model outputs. Numerical simulation is useful not only to study the inland propagation, but also to analyze the thermal internal boundary layer, the head wind and all the interesting components of the sea breeze circulation phenomena, including the transport of pollutants inside it.
