RESEARCH INTERESTS and FIELD PROJECTS

• Investigating atmospheric oxidants, especially halogen chemistry, and dynamics from changes in composition of nonmethane hydrocarbons and halocarbons and using detailed photochemical point (box) models during aircraft campaigns near the Azores in the North Atlantic (NSF sponsored ASTEX/MAGE),  over the Southern Ocean (NSF ACE-1), and the  Central Pacific (NASA GTE PEM-Tropics A).  These processes are important in understand  the lifetimes and degradation processes of radiatively important trace gases such as dimethyl sulfide (DMS).
• Quantifying anthropogenic versus natural emissions of stratospheric ozone depleting gases such as methyl bromide (CH₃Br; global, Arctic, Southern Ocean, and in New Mexico) and gases important to climate from various sources.  Platforms include land, ship, mesocosms, and aircraft.
• Future, past and geo-engineered climates are studied using perturbation experiments simulating for example during
• SOFeX, The Southern Ocean Iron  Fertilization Experiments (see also  reprint of PNAS paper)
• PeECE III, a mesocosm experiment studying the effects of future increased CO₂ concentrations on ocean acidification and the perturbation to marine microorganisms and trace gas fluxes
• Air Quality - measuring and modeling constituents important to urban and regional air quality.  Areas studied while at New Mexico Tech include New England, Albert, Canada, Taiwan, and local areas.
