- 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. -

We apply GEOS-Chem for a range of applications in - atmospheric chemistry, including supporting the retrieval and interpretation of - satellite observations of atmospheric composition in the context of in situ - measurements. We collaborate with the GEOS-Chem community, especially - with Harvard, in the development of GEOS-Chem. We also support the - application of GEOS-Chem by the user community.
