Narrative:
My research efforts over the past 20 years have centered primarily on the development, application, and evaluation of Eulerian and Lagrangian air quality models on urban to regional scales. Recently, I have been using the Community Multiscale Air Quality (CMAQ) model to investigate the impact of recent real-world emission changes and meteorological variations on surface ozone concentrations in the eastern U.S. I have also participated in a model evaluation team effort to advance and apply a variety of evaluation approaches. In particular, my current work involves using dynamic evaluation to examine modeled and observed changes in concentrations over multiyear periods, and diagnostic methods to investigate various physical processes and chemical production through comparisons of modeled meteorological parameters and concentrations to available measurements. My research project within the CMAQ model development effort was to incorporate and evaluate a sub-grid plume (plume-in-grid) module capable of realistically treating the dynamic, photochemical, and aerosol processes governing concentrations in the plumes emanating from major point sources with high rates of nitrogen oxide (NOx) and sulfur oxide (SOx) emissions.
