New Publication: Simulating Aqueous-Phase Isoprene-Epoxydiol (IEPOX) Secondary Organic Aerosol Production During the 2013 Southern Oxidant and Aerosol Study (SOAS)

We’re thrilled to announce the publication of the second paper to result from our collaboration with fantastic scientists at U.S. EPA and UNC on modeling the data from the Look Rock, TN ground site during SOAS 2013. This work was supported by U.S. EPA through its Office of Research and Development.

New McNeill review article: ‘Atmospheric Aerosols: Clouds, Chemistry and Climate’

We’re happy to announce the publication of VFM’s new review article, ‘Atmospheric Aerosols: Clouds, Chemistry and Climate,’ as a Review in Advance online in the Annual Review of Chemical and Biomolecular Engineering. The final version of the article should appear online in July 2017.

This article reviews fundamental concepts and recent developments surrounding ambient aerosols, their chemical composition and sources, light-absorbing aerosols, aerosols and cloud formation, and aerosol-based solar radiation management (also known as solar geoengineering). Summary points include:

1. Atmospheric aerosol particles impact Earth’s climate by scattering and absorbing solar radiation and by influencing cloud formation and properties.
2. The chemical composition of ambient aerosols and their chemical transformations in the atmosphere impact their climate-relevant physical properties.
3. Rapid discovery in this area over the past two decades has been enabled by advances in technology for characterizing aerosol chemical composition and physical properties.
4. Future challenges and opportunities lie at the interface of atmospheric chemistry and computer science.

New Publication: The Essential Role for Laboratory Studies in Atmospheric Chemistry

Prof. McNeill is a coauthor on this newly accepted Feature article in Environmental Science & Technology:

The Essential Role for Laboratory Studies in Atmospheric Chemistry

James B. Burkholder, et al. Environ. Sci. Technol. (2017), Just Accepted Manuscript, DOI: 10.1021/acs.est.6b04947
From the abstract:
Laboratory studies of atmospheric chemistry characterize the nature of atmospherically relevant processes down to the molecular level, providing fundamental information used to assess how human activities drive environmental phenomena such as climate change, urban air pollution, ecosystem health, indoor air quality, and stratospheric ozone depletion. Laboratory studies have a central role in addressing the incomplete fundamental knowledge of atmospheric chemistry. This article highlights the evolving science needs for this community and emphasizes how our knowledge is far from complete, hindering our ability to predict the future state of our atmosphere and to respond to emerging global environmental change issues. Laboratory studies provide rich opportunities to expand our understanding of the atmosphere via collaborative research with the modeling and field measurement communities, and with neighbouring disciplines.

McNeill Group Research Featured in J. Phys. Chem. A Virtual Special Issue on Atmospheric Physical Chemistry

Our 2013 paper on the photochemical aging of aerosol brown carbon has been featured in a virtual special issue of the Journal of Physical Chemistry A, on Atmospheric Physical Chemistry. From the editor:

It is the vision of this editor that the current collection may serve as a useful tool for generating new ideas, pushing existing boundaries, and motivating new research in atmospheric chemistry. Moreover, this virtual issue may serve as a basis for putting together or updating a graduate course on atmospheric physical chemistry.
