Novel analytical approaches to characterizing the composition and source of aerosol brown carbon

Dr. Cora Young, Assistant Professor in the Department of Chemistry at York University, presented their research into the chemical drivers of climate and the fate and transport of contaminants at the SOCAAR Seminar held on January 10th, 2018. The talk gave insights on the molecular composition of brown carbon, aging, and the limitations of mass spectrometry in detection and characterization of brown carbon.

It’s well known that the Arctic climate is influenced by anthropogenic contributions like heating during the winter and regional sources in the summer. But the chemistry of the aerosol environment and its influence on the cloud formation over the Arctic is less understood. Dr. Julia Burkart and Megan Willis, a postdoctoral fellow and Ph.D. student respectively, at the University of Toronto’s Department of Chemistry presented findings from their NETCARE summer aircraft campaign in Resolute Bay, Nunavut at the SOCAAR Seminar held on November 5.
