Old Bridge's air quality reflects the Raritan Bay coastal position in Middlesex County New Jersey, with vehicle emissions from the Garden State Parkway and the surrounding suburban residential and industrial corridor contributing local sources. The Raritan Bay maritime influence provides periodic ventilation from the south, while the broader New York-New Jersey metropolitan area's regional ozone and PM2.5 on prevailing southwesterlies elevates background pollution above the New Jersey coastal baseline throughout the year.

When is air pollution at its worst in Old Bridge?
Seasonal changes shape air quality across Old Bridge: winter generally brings the cleanest air, once the summer ozone season has passed, but extended summer heat waves, often worsened by regional haze, bring the toughest air quality stretch. Dense urban traffic corridors add a persistent background level of pollution that varies less by season than ozone does.
Are air quality levels in Old Bridge 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.
