AICI 2011 Archive
The 3rd Workshop on Air-Ice Chemical Interactions (AICI) was held at Columbia University June 6-8, 2011. International AICI workshops bring together field, modeling, and laboratory scientists studying the atmospheric chemistry of ice and snow. Three days of talks and posters focused on the following topics:
- Organics in Environmental Ices
- Halogen Activation in the Polar Boundary Layer
- Snow and Ice Microstructure
- Snow Chemistry Modeling
Review articles generated from this workshop will appear in a special issue of Atmospheric Chemistry and Physics entitled “New Perspectives on Air-Ice Chemical Interactions (AICI)” edited by V. Faye McNeill, Thorsten Bartels-Rausch, and Eric Wolff.
