Towson's air quality reflects the Baltimore County suburban position north of Baltimore's urban core, with vehicle emissions from I-695 Beltway and the surrounding government, education, and commercial corridor contributing local sources. The Chesapeake Bay's maritime influence provides limited ventilation from the east, while the broader Baltimore-Washington mid-Atlantic regional airshed contributes elevated summer ozone and the flat suburban Maryland terrain generally allows reasonable wind dispersal throughout the year.
