Trenton's air quality reflects New Jersey's most densely industrialised state corridor, with vehicle emissions from I-95 and the surrounding New Jersey Turnpike generating heavy freight NOₓ and the Delaware River's historic industrial legacy contributing background PM2.5. The Delaware River provides limited ventilation, while Trenton's position in the busy mid-Atlantic transportation corridor between Philadelphia and New York means it experiences elevated regional background pollution throughout the year.

When is air pollution at its worst in Trenton?

Trenton follows a fairly predictable seasonal air quality pattern: once summer ozone season ends, winter typically offers the cleanest air, but summer heat waves bring the highest ozone risk, compounded by pollution drifting in from the wider region. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.

Are air quality levels in Trenton 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.
