The deposition processes determines the lifetime of a variety of gases and particles in the atmosphere. Computed depositions depend highly on the parameterisation and model concept. A vertical resolution of the tested model influences not only directly the description of dry and wet deposition processes, but also indirectly, as the chemical reactions are affected by the vertical distribution of gases and particles in the PBL. This indirect influence is due to the common assumption of full mixing in the PBL in models of no or only coarse resolution in the vertical. The effect of the vertical model resolution on estimations of concentrations and depositions of gases and particles is the subject of this paper.
