McNeill Group @ Columbia University

McNeill Group @ AAAR 2016!

dreamstime_xxl_14560630This time of year is like Christmas for aerosol scientists – it’s time for the 35th Annual AAAR Meeting!  The meeting, which will be held in Portland, OR, this year, highlights cutting edge research in all areas of aerosol science. The McNeill Group will be well-represented this year, with several platform and poster presentations.  Hope to see you in Portland!

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.


First direct detection of organics at the aerosol surface – our new publication in J. Phys. Chem. Lett. !

Picture1We are very happy to announce the publication of our exciting new results demonstrating the first direct detection of organic material at the gas-aerosol interface. This article is the first publication to result from the Columbia-Temple NSF Photoactivator collaboration.

AIRE gets a new look

AIRE screenshotOur outreach website, AIRE, has a new look!

AIRE is an acronym for “Atmospheric Information Resource for Educators and students” and is also Spanish for “air.” This website has been active since 2008 (under its former name, “Science of the Atmosphere,” until 2014). Our goal is to provide interesting, accessible, scientifically accurate information about our changing environment. We post and tweet in two languages (English and Spanish).  Follow AIRE on twitter at @AIRE_outreach.

Photoactivator Team Meeting

Today we had a very productive meeting with our collaborators from Temple University for an update on our joint NSF project, “Photoactivator Chemistry in Atmospheric Aerosols” (CHE-1506789).
