Research Interests

Measuring and understanding changes in the chemical composition of the global atmosphere, particularly related to ozone-depleting substances, greenhouse gases, and hazardous air pollutants; identifying the role of natural and human-related influences on hemispheric to global-scale atmospheric composition; diagnosing variability in the atmosphere's oxidizing capacity, in terrestrial photosynthesis, and in stratosphere-troposhere exchange; quantifying fluxes of trace gases from the United States; and effectively communicating scientific results via national and international assessment reports.

Current Research

Interpreting observations from a multi-decadal sampling program for over 30 trace gases at 45 sites distributed throughout the global atmosphere is a continuing theme.  Data obtained from measurements of these samples via high-precision gas chromatography coupled to mass spectrometry have been used recently for 1) investigating the influence on the ozone layer of increasing concentrations of short-lived gases not controlled by the Montreal Protocol (e.g., dichloromethane), 2) diagnosing the global and relative hemispheric concentration of the hydroxyl radical, over time and estimating the impact of those changes on the global budget of methane, 3) improving our understanding of the global budget of carbonyl sulfide, which may enhance our understanding of CO2 uptake by terrestrial photosynthesis, and 4) documenting broad-scale concentration changes in short-lived trace gases influencing ozone and air quality.

In addition to studying atmospheric changes on global scales, the U.S.-centric sampling program managed by the Carbon Cycle Group and NOAA has allowed investigations into national-scale issues.  Data obtained from this regional network have been used to quantify national-scale emissions of ozone-depleting substances and non-CO2 greenhouse gases so as to 1) provide estimates independent of inventory-based methods ozone-depleting gases and substitute chemicals, in particular), 2) improve the quantification and attribution of atmospheric impacts associated with oil and gas exploration and development (including hydraulic fracturing), and 3) improve our understanding of continental-scale sources and sinks of carbonyl sulfide, a trace gas whose concentration changes over land to appear closely linked to terrestrial photosynthesis.
