Abstract
Aerosols in the atmosphere play a critical role in determining the fate of atmospheric pollutants
and also influence global climate change. Fog is a lower atmospheric, near-surface cloud and
plays a role in determining local weather patterns. In this respect fog-processing of organic
chemicals is important to understand. Relatively little is known about the organic composition
of fog in many parts of the world and approximately 50% of material in fog has not been
characterized. Atmospheric transformations in a foggy environment are driven by heterogeneous
reactions in thin water films (< 10μm), which have been largely unexplored. Our laboratory has
been engaged in a six year field and laboratory project understanding the chemistry of fog in the
Gulf Coast region between Houston and Baton Rouge. This seminar will summarize our recent
work in this field.
