Newark's air quality faces significant challenges as New Jersey's largest city in the heart of the New York-New Jersey industrial corridor, with the Port Newark-Elizabeth Marine Terminal and Newark Liberty International Airport generating concentrated diesel and aviation PM2.5 alongside heavy goods vehicle traffic on I-78 and I-95. The Passaic and Hackensack river corridors provide limited ventilation, but Newark's industrial port position consistently produces some of the New York metropolitan area's highest sustained pollution readings.

When is air pollution at its worst in Newark, New Jersey?

Conditions in Newark vary noticeably across the seasons, as the calmest air of the year usually arrives well after the summer ozone season fades; by contrast, the hottest, most humid summer weeks bring the year's highest ozone readings. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.

Are air quality levels in Newark, New Jersey 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.

Why doesn’t the forecast always reflect wildfire impacts?

Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.

During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
