Abstract We present preliminary results from the integration of the MOSAIC aerosol model into the Environment and Climate Change Canada online air quality model, GEM-MACH. MOSAIC includes nucleation, coagulation, non-equilibrium mass transfer and thermodynamics. Three simulations with constrained meteorology are conducted with the MOSAIC version including bin-resolved, mode-aggregated (nucleation-Aitken, accumulation and coarse) and bulk treatment of the thermodynamics and inter-compared with each other and against the reference GEM-MACH model with bulk thermodynamics.
