Quality
• Development of air quality modelling capacity to simulate shipping and other sectors in the Arctic
• Ambient air quality monitoring for evaluation of model meteorology and air quality predictions
• Modelling of a number of emissions scenarios at various spatial and temporal resolutions
Preliminary GEM-MACH Arctic simulation, using 2005/2006 U.S./Canadian anthropogenic emission inventories, chemical boundary conditions from seasonal averaged global GEM-MACH model results.

Research Questions
• How do ship emissions disperse into the boundary layer under different conditions?
• Do ship traffic emissions have a measurable effect on air quality in Arctic communities?
• How is this effect expected to change in the coming decades?
