It’s our favorite week of the year, the Annual Meeting of the American Association for Aerosol Research (AAAR)! Catch the following presentations of McNeill group work at the meeting in Orlando, FL:
The final version of our manuscript, Climate-relevant physical properties of molecular constituents relevant for isoprene-derived secondary organic aerosol material, was published today in Atmospheric Chemistry and Physics! This work was a result of a collaboration between the McNeill Group and the Geiger and Thomson groups at Northwestern University (the Geiger group led the project) . This work shows that oxidation products of isoprene, a volatile organic compound emitted in large quantities by plants all over the world, can form films on the surfaces of aerosol particles and depress their surface tension. This effect can lead to enhanced cloud formation and suppressed aerosol heterogeneous chemistry.

We’re very happy to announce an initiative to revitalize the McNeill Group outreach website, newly renamed “AIRE.” AIRE is an acronym for “Atmospheric Information Resource for Educators and students”, and is also Spanish for “air.” We will use this new platform to continue our efforts to bring easy-to-understand, scientifically accurate information about the atmosphere, air pollution, and climate to the public in two languages (English and Spanish). You can also follow AIRE on twitter at @AIRE_outreach.
AIRE: Atmospheric Information Resource for Educators and students
The McNeill Group welcomes two new Masters’ students and three new undergraduate students to the group: Welcome Jamal, Chunhui, Kopi, Annie, and Su Anne!
Prof. McNeill attended an event titled “Leaders’ Forum on Women Leading the Way- Raising Ambition for Climate Action” on Monday Sep. 22. The event was hosted by UN Women and the Mary Robinson Foundation – Climate Justice in conjunction with the UN Climate Summit 2014.
Panel discussion led by Mary Robinson, former President of Ireland and UN Special Climate Envoy, which included Christiana Figueres of UNFCCC
Academic attendees L to R: Raul Lobo, U. Delaware, VFM, Jaehong Kim, Yale, and Laura Fabris, Rutgers
We’re excited to announce the publication of our newest paper, “Model Analysis of Secondary Organic Aerosol Formation by Glyoxal in Laboratory Studies: The Case for Photoenhanced Chemistry.” This manuscript, which describes a critical analysis of results from aerosol chamber studies in the literature using the McNeill Group GAMMA model, appeared this week as a “Just Accepted Manuscript” in Environmental Science & Technology. This paper is the result of work done by Andrew Sumner while he was an undergraduate in the Chemical Engineering department at Columbia University. Andrew just started a PhD program at Yale. Congratulations Andrew!

Today was the last day for our high school summer volunteers, Izzy and Lucy! The dynamic duo wrapped up their work with a #flawless final presentation. They made great progress on the Oil Spill project over the last few months. We will miss you two!

We’re pleased to announce the publication of our latest research article as a Just Accepted manuscript in J. Phys. Chem. C. This article is part of the John Hemminger Festschrift.
The interaction of volatile organics with ice is a major factor influencing atmospheric composition in Polar regions. We have shown for the first time that exposure to HCHO and CH3CHO induces changes in the ice surface state, including the formation of a disordered interfacial layer and opaque domains, at environmentally relevant conditions. These findings have significant implications for our understanding of the interactions of these trace gases with ice, and the interpretation of snow pit and ice core chemical records.
