Abstract

An algorithm for size-distributed atmospheric aerosols designed for the Northern Aerosol Regional Climate Model [NARCM] is applied to three versions of the Canadian climate models: GCM, RCM and FIZ-C/LCM. It incorporates the processes of aerosol generation, diffusive transport, transformation and removal as a function of particle size to simulate global and regional sea-salt aerosol spatial and temporal distributions. A comparison was made between observations and model predictions of sea-salt. Size-resolved aerosol properties such as transport patterns, fluxes and removals are obtained from the simulations. Since the sea-salt generation term is relatively well quantified, the comparison ensures that a reasonable parameterization of removal and transport schemes is used.
