Abstract

This study presents the development of a new 3D size-composition resolved aerosol model (SCRAM). It solves the aerosol dynamic evolution for external mixtures taking into account the processes of coagulation, condensation/evaporation and nucleation. Both the size of particles and the mass fraction of each chemical compound are discretised. For a given particle size, particles of different chemical compositions may co-exist. Chemical components can be grouped into aggregates to reduce computational cost. SCRAM is coupled to the air quality model Polair3d/Polyphemus, and its performance to model air quality over Greater Paris is evaluated, as well as the consequences of the internally mixed assumption on aerosol distribution, composition and optical properties.
