Canadian Meteorological Center
Dorval, Quebec, Canada

Air Quality Research Division

The Air Quality Research Division of Environment and Climate Change Canada (ECCC) has launched a project to update the aerosol model in GEM-MACH, the ECCC air quality model. This includes revising parameterizations for nucleation and post-nucleation growth including the role of organics, thermodynamics, and improving the mixing state representation based on the latest research. Substantial advances have been made over the last 10 years in understanding nucleation and the role of organics but existing aerosol models represent the state of the art that dates back to the 1990s. One of the major limitations of existing aerosol models is the treatment of sub 100 nm particles which become increasingly surface active and impacted by the Kelvin curvature effect. Existing thermodynamics models and aerosol dynamics models fail to properly account for size effects. Yet sub 100 nm particles are important for health impacts and aerosol indirect effects via CCN formation.

Our research mainly focuses on the study of air pollution (gases and aerosol) in global and regional scale as well; in the last case, GEOS-Chem with nested-grid capabilities is applied over Europe to study CO, O3, aerosol and other species concentrations levels. One of our recent works involves model's results for AEGEAN-GAME airborne campaign, which took place over the Aegean Sea in Greece (Eastern Mediterranean) during an Etesian wind regime period (September 2011). More model results is planned to be provided in high resolution for other field campaigns, too.

The coupling procedure of GEOS-Chem with other models (UAM-V, PMCamx) has been developed for Greece by providing initial and boundary conditions to the meso-scale models and by matching the two models' chemistry mechanisms. Moreover, the global model was applied to assess the impact of aircraft emissions on O3 and NOx, examine the N. American and Asian emissions' contribution on European budget and the European outflow towards the Eastern Mediterranean.

Climate change impacts, under the A1B emissions scenario, in European air-quality for the 2050 future period are also assessed using the GEOS-Chem global transport model driven by meteorological fields from the GISS/GCM. We focus in the possible responses of European air quality both due to climate change alone and due to the combined effects of climate change and changing future air pollution emissions.
