SSH-aerosol models aerosol formation from gaseous precursors and its evolution. It can simulate the mass of aerosols, the partitioning of semi-volatile compounds as well as the mixing-state and number concentrations of particles. It is designed to be easily implemented in 3D Eulerian models, such as air-quality models, or to be used as a box model to estimate the formation of secondary aerosols (gas and particle phases). It takes into account known phenomena involved in the formation of aerosols. The model is modular and the user can choose the complexity required (the physical and chemical processes taken into account). The model will be distributed in fall 2019. The model is based on the merge of 3 state-of-the-art models: SCRAM, SOAP and SSH...
