Lisa goes to FIREX-AQ

Lisa started her 3-month participation in the FIREX-AQ campaign last week. She will be making measurements from the Twin Otter aircraft (“Chem Otter”) to better understand brown carbon produced from wildfires. She will be working closely with collaborators from NOAA and the University of Colorado. Lisa will be spending ~6 weeks in Boulder, CO preparing the measurement system before travelling to Boise, ID to undertake the research flights. Her trip is being funded through a Mitacs Globalink Award. Good luck Lisa!

HaliFAQS campaign begins!

The Halifax Fog and Air Quality Study (HaliFAQS) began recently at St. Mary’s University in Halifax, NS. This project is a collaboration with the research groups of Aldona Wiacek (SMU) and Rachel Chang (Dalhousie) aimed at better understanding the role of ocean-atmosphere exchange on air quality and fog formation. Alex and Teles are heading our group’s contribution with several gas and aerosol phase measurements.Looking forward to seeing the results!

Welcome (back) Lisa and congratulations!

The group is pleased to welcome Lisa Azzarello as an MSc student! Lisa joined the group as an undergraduate student and is back with us for an MSc, where she will be examining the chemical composition of aerosols and the impact on climate. Lisa was also recently awarded a Mitacs Globalink Research Award that will take her to Colorado and Idaho this summer/fall to participate in the FIREX-AQ field campaign with collaborators at the University of Colorado and NOAA. Congratulations and welcome back!

Welcome Alex!

Welcome to our new postdoc, Alex Moravek! Alex did a PhD at Max Planck Institute for Chemistry and more recently has been working at the University of Toronto. Alex brings expertise in measurement of reactive gases and biosphere-atmosphere exchange. We are excited to have him join the team.

Cora at Harvard

Cora was in Boston last week to give an invited seminar at Harvard in the Department of Earth and Planetary Sciences. She presented Heidi’s perfluoroalkyl substances work, along with reactive chlorine work from Teles, Andrea, and Kathryn. Along with meeting many fantastic faculty and students, she was able to tour group alum Heidi’s new workplace!

Indoor chem chamber studies in Syracuse

Cora was in Syracuse recently to participate in chamber experiments with collaborators Tara Kahan, Jianshun Zhang, and Trevor VandenBoer. The experiments, known as Radicals and Oxidants from Cleaning in a Chamber (ROCC) were undertaken in the specialized chamber in Prof. Zhang’s lab. These are part of a larger project funded by the Alfred P. Sloan Foundation.

Kathryn's paper published!

Kathryn’s paper, describing cavity ring-down measurements of HCl indoors, was published recently in the journal Indoor Air. Kathryn identified several sources of HCl indoors, including bleach, dishwasher use, and cooking, showing evidence for direct emissions and potential for indirect formation. This work was part of a collaboration with Tara Kahan’s group at the University of Saskatchewan (formerly Syracuse University).
