Atmospheric pollution at the regional scale must accommodate emissions from different sources, urban sources at the city center and its industrial suburbs as well as rural-type sources in residential areas, parks and adjacent cultivated zones. Typically, atmospheric pollution at the regional scale (mesoscale) is a problem of mixed sources with the emitted chemical species being transported and transformed within the regional breezes and orographic circulations triggered at the mesoscale. In particular we are interested in the study of air pollution in the region of Sfax. Sfax is an industrial town at the Mediterranean shores of Tunisia surrounded by extensive olive tree groves. One can thus expect a strong interaction between emissions of natural Hydrocarbons (HCs) (from the olive tree fields) and NOx / anthropogenic non-methane HCs (NMHCs) from the urban and industrial areas of Sfax. Differential deposition on sea and land surfaces, sea-breeze circulations and turbulence generated by surface heating have to be taken into account. This presentation is devoted to a discussion of sensitivity tests of the chemical module together with its emission and deposition parameterisations chosen for the Sfax scenario.
