A fully coupled on-line air quality forecast model, GEM-MACH, was used to study a case of cloud processing in an urban-industrial plume and aerosol-cloud-meteorology interaction. Preliminary results have shown a significant impact on modelled clouds and particulate sulfate concentrations due to the inclusion of the feedback from on-line aerosols to microphysics. Further tests and detailed comparison with in-situ measurements of this case are underway.
