The Regional Chemical Modeling program undertakes research that improves our ability to forecast regional air quality in the lower troposphere, and increases our understanding of the free tropospheric ozone budget.
Our primary research tool is the WRF-Chem chemical transport model with which we develop and evaluate state-of-the-art capabilities to describe the emission, transport and chemical evolution of pollutants in the atmosphere. We evaluate the model's performance with comparison to measurements of ozone and particulate matter made during integrated field studies. Related topics include examination of the impact of pollutants on low level cloud formation, and the influence of coastal dynamics on pollution export from North America. Beyond the continental and marine boundary layer we combine hemispheric scale tracer transport studies, satellite observations, and both coordinated and opportunistic measurements to improve our understanding of the North American free tropospheric ozone budget.
