Disclaimer The Canadian Arctic is vast and varied This is not a comprehensive compendium of all relevant research - it is a sample of things that are going

2 Disclaimer The Canadian Arctic is vast and varied This is not a comprehensive compendium of all relevant research - it is a sample of things that are going on at present. Contributions from Paul Kushner, Claude Labine, Environment Canada, Pierre Fogal, the PEARL team and other sources are gratefully acknowledged

3 Some of the Major Players in Atmospheric Research in Canada Government (may have monitoring and regulatory interests) Environment Canada (Federal) Natural Resources Canada (Federal) Canadian Space Agency (Federal) Provincial and territorial governments (e.g. Nunavut Research Institute) Universities and similar organisations Natural Sciences and Engineering Research Council Canadian Foundation for Innovation Climate Change and Atmospheric Research (CCAR) projects, esp. PAHA, NETCARE, CanSISE Networks of Centres of Excellence, e.g. ArcticNet University sponsored stations e.g. Kluane Lake Research Station, McGill Arctic Research Station Other Organisations Canadian Polar Commission (CPC) Northern Contaminants Program (NCP) Canadian Network of Northern Research Operators (CCNRO) ArcticNet Canadian High Arctic Research Station (CHARS)

4 Major Research Foci Climate Change State and prediction of loss Ocean-ice-atmosphere interactions Greenhouse Gases Atmospheric increases Production and release from the surface Impacts of warming on release of stored methane and CO2 Energy Budget Sea Ice Emphasis on mitigation and adaptation Impact on communities, social impacts Closing the energy budget in all seasons over ice, snow, ocean and land Air Quality Intrusion of pollutants from lower latitudes to Arctic Impact on biosphere Ozone Changes Interaction with climate Upper Atmosphere Magnetic Polar influences, solar influences, auroral activity

9 Some Sample Projects Arctic ocean and sea ice flux measurements "Wintertime CO2 fluxes in an Arctic polynya using eddy covariance: Evidence for enhanced air-gas transfer during ice formation. (JGR) - Tim Papakyriakou, University of Manitoba Main area has been the SE Beaufort sea and Amundsen Gulf region and some papers will be coming out next year for Baffin Bay and the North Water Region. Working on EC (Eddy Covariance) derived fluxes over different sea ice environments. "Convective forcing of mercury and ozone in the Arctic boundary layer induced by leads in sea ice (Nature) Ralf Staebler, EC Collaborating with the OASIS group and with AWI/NETCARE

10 More Sample Projects Ice and Snow: CO2, methane flux and energy budget studies near Lake Hazen - Vincent St Louis, University of Alberta. Climate based work on Agassiz Ice Cap - NRCan's glaciologist David Burgess, at Alexandra Fiord with Greg Henry, bio geographer UBC and at Polar Bear Pass with Kathy Young, hydro-meteorologist, York University. Climate geomorphology, permafrost and life in extreme environments on Axel Heiberg Island - Wayne Pollard - McGill University Weather/Climate Stations Centre d'étude Nordique, Université Laval has an extensive network of weather/climate stations stretching from northern Quebec to Bylot Island and Ward Hunt Island part of ArcticNet Polar Environment Atmospheric Research Laboratory (PEARL) at Eureka in conjunction with the Eureka Weather Station Canadian High Arctic Research Station (CHARS) in Cambridge Bay (2017)

20 PEARL/CANDAC/PAHA Themes In all these themes there is a strong emphasis on the Polar Night Composition Measurements Theme Leader Strong Greenhouse Gases related to the Carbon Cycle Ozone and Related Species Biomass Burning and continental influence on the Arctic Clouds, Aerosols and Precipitation Polar Night Theme Leader Sica The Wintertime Environment The Polar Vortex Satellite Validation Theme Leader - Walker

21 PEARL/CANDAC/PAHA Resources The dataset from Eureka from inception of: the weather station (1947+), ASTRO (~ ) and PEARL (2005+) PEARL and its associated instrumentation (25+ instruments spanning the entire atmosphere) Links to other Arctic stations through the Integrated Arctic Stations for Observing the Atmosphere (IASOA) initiative (under SAON) Other (inter)national collaborations
