Research Interests:
My research interests focus on global and regional atmospheric impacts of anthropogenic pollutants and boreal wildfires and the interactions of snow, ice, air and light. The global budget and cycling of nitrogen oxides plays a dominant role in the budget of tropospheric ozone and, through ozone, is a determinant of tropospheric oxidative strength. However, measurements of nitrogen oxides in remote regions (most of the earth) are extremely limited. By making measurements in these regions, we are able to test current understanding of tropospheric photochemistry. Such direct measurements often result in significant modification of our understanding of tropospheric fate and cycling of nitrogen oxides and other species. For example, in 1998 we discovered that NOx is released to the atmosphere from sunlit snow in the Arctic and at mid-latitutes. My research group and I are currently focusing on two sets of projects aimed at assessing the impacts of anthropogenic emissions and boreal wildfires on ozone and ozone precursors at the hemispheric scale. We are using field measurements at the Pico Mountain station in the Azores Islands in combination with transport and chemical transport model (GCTM) simulations, and novel new techniques combining the two types of models, to probe the impacts of outflow from the United States and other source regions on ozone and ozone precursors over the remote North Atlantic Ocean and to assess the consistency of these measurements with GCTM simulations. We are also conducting a series of field studies in the Arctic and in subarctic regions, to constrain the impacts of long-range transport of anthropogenic and biomass-burning emissions on the composition of the arctic lower free troposphere and to develop models of NOx release and ozone destruction in snowpacks.
