New Haven's Yale University Campus air quality benefits from the extensive campus greenspace and collegiate Gothic courtyards providing natural filtration against the surrounding New Haven urban development. Vehicle traffic on the surrounding Chapel Street and Elm Street corridors contribute local sources, while the campus's mature tree canopy and green quadrangles generally maintain better conditions than the surrounding dense commercial corridors and the Long Island Sound coastal influence provides background maritime ventilation.
