EARTH SYSTEMS SCIENCE
Atmospheric Chemistry Focus
Field and laboratory studies focus on understanding the distribution, sources, and fate of atmospheric gases and particles, and their role in global climate.

Field studies in the Western Pacific, South America, and Arctic;
Global Tropospheric research;
Modeling studies of climate change-chemistry interactions;
New analytical techniques development;
Source identification for greenhouse gases.
