Research
My research is focused on modeling tropospheric chemistry at the local and regional levels.
Our currently funded research project entails the evaluation of a CMAQ-based regional model for the assessment of transport and deposition in and around the Great Lakes. Such regional model assessments are necessary in order to supply confidence in models as a tool to aid in the design of mitigation measures required for improving the health of lake ecosystems in the region. The focal area for this model evaluation study is upstate New York, and its border with Lake Erie and Lake Ontario. The model will be evaluated by comparison of modeled values to measured ambient concentrations of particulate matter (PM2.5), mercury (Hg) and speciated polycyclic aromatic hydrocarbons (PAH) as reported by Hopke et al. [2003] for the summers of 2000 through 2003, as well as the less intensive mercury campaign described by Han et al. [2004]. Initial modeling work will focus upon comparisons to field measurements for the summer of 2002, with additional modeling work aimed at attributing possible ('future') changes in emissions levels to modeled deposition within the region. This project represents a collaborative effort between SUNY-Fredonia and the New York State Department of Environmental Conservation (NYSDEC).
