Atmospheric & Environmental Chemistry Seminar

John Abbatt, University of Toronto, will discuss "Exploring Aerosol in the High Arctic: Evidence for Substantial Nucleation and Growth in the Summer."

The Arctic is a bellwether for climate change, now experiencing substantial summer sea ice melt.  The impacts of this transition from an ice covered regime to an open summer ocean may have impacts on aerosol, cloud and climate.   With this as motivation, the Canadian NETCARE research network undertook two field campaigns in the Arctic to study the nature of aerosol in this remote environment, in both the Arctic Haze-dominated springtime season and also the much cleaner summer period.  Results will be presented from both campaigns, with an emphasis given to the summertime measurements that show clear evidence for local aerosol sources, arising from nucleation and growth occurring in marine and coastal regions.  Although nucleation and growth does not frequently occur in lower latitude marine boundary layers, such events occur frequently within the persistent inversion layer in the Canadian Arctic.   Connections to the properties of low-level clouds will also be made.
