An aerosol module is developed to simulate physicochemical behaviour of regional/urban particles. The module takes into account equilibration of inorganic particulate matter including sea salt and crustal elements. The solver of the equilibrium equations is tested on cases described in the literature.

The size distribution of the particles is described with three overlapping lognormal distributions. Changes in the particle size modify the shape of the distributions by corresponding corrections of the geometric mean and standard deviation of the distributions. The algorithms describing the dynamic processes affecting particle size distribution such as condensation and coagulation are tested against more accurate numerical approaches that have been used for other aerosol models evaluation. .
