Gloucester's air quality reflects the Delaware River waterfront position in Camden County New Jersey, with vehicle emissions from I-295 and the surrounding industrial and residential character contributing local sources. The Delaware River provides limited ventilation, while the broader Philadelphia mid-Atlantic regional airshed contributes elevated summer ozone from the Delaware Valley industrial and urban sources throughout the year.

When is air pollution at its worst in Gloucester?
Like most US cities, Gloucester sees air quality shift from season to season, as once summer ozone season ends, winter typically offers the cleanest air; by contrast, extended summer heat waves, often worsened by regional haze, bring the toughest air quality stretch. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.
Are air quality levels in Gloucester based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
