The Mid Atlantic States suffer experience high levels of ozone and particulate matter associated with photochemical smog and haze. Interstate transport as well as the proximity to large water bodies and natural forests complicate the meteorology and chemistry of pollution formation and spatial scales. We describe an integrated approach of in situ and remote sensing to constrain and refine numerical models to better simulate past atmospheric chemistry and future air quality. Findings include the role of the sea and bay breezes, NOx sequestering and release from reservoir species such as isoprene nitrates, and corrections to emissions of key precursors. The results have been used by policy makers to substantially improve air quality in the East and are being extended to studies of greenhouse gas emissions.
