We are happy to announce that our paper on simpleGAMMA is now available online! We welcome your comments.
simpleGAMMA is currently being used to analyze data from SOAS 2013, and we are working with collaborators to couple simpleGAMMA with regional and global scale 3D atmospheric chemistry models – please contact Prof. McNeill (email@example.com) if you are interested in using simpleGAMMA or learning more about it.

Our publication, “Organic matrix effects on the formation of light-absorbing compounds from α-dicarbonyls in aqueous salt solution“ (Drozd and McNeill, ES:PI 2014) has been included in a special collection of research papers, review articles, and themed collections on the subject “Chemistry in Climate Change” by the Royal Society of Chemistry. Our paper and all the others in this excellent collection can be read and downloaded for free from the RSC until December 20th, 2014.
Here are a few other articles from the collection that we recommend:
- Global air quality and climate, a review in Chem. Soc. Rev. by our Columbia collaborator Prof. Arlene Fiore
- Chemical signals of past climate and environment from polar ice cores and firn air a review in Chem. Soc. Rev. by Prof. Eric Wolff of U. Cambridge
- Gas–particle partitioning of atmospheric aerosols: interplay of physical state, non-ideal mixing and morphology by Prof. Manabu Shiraiwa of the Max-Planck Institut
- Volatile organic compounds in Arctic snow: concentrations and implications for atmospheric processes by Prof. Parisa Ariya and colleagues at MacGill University
We are very happy to announce a new publication from our collaboration with Prof. Ilona Riipinen of Stockholm University! Silja Hakkinen, a Ph.D. student at University of Helsinki who is supervised by Prof. Riipinen, visited our laboratory from Summer 2012- Summer 2014 as a Fulbright Scholar. This paper is result of some of the fantastic work she did during that time. Great work, Silja!

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.
The McNeill Group welcomes two new Masters’ students and three new undergraduate students to the group: Welcome Jamal, Chunhui, Kopi, Annie, and Su Anne!
