The Raff Laboratory

The long-term goal of our work is to improve our understanding of the sources and sinks of nitrogen oxides (e.g., NO, NO2, HONO, N2O5, and N2O) on ground surfaces, thereby enabling more accurate representation of nitrogen terrestrial-atmospheric exchange in predictive models used to understand the climate system and to protect human health from the effects of air pollution. We seek to understand the fundamental chemical mechanisms and biogeochemical processes responsible for how these trace gases behave in the environment using an approach that integrates controlled laboratory experiments and field measurements and utilizes state-of-the-art analytical methods.
