Jacksonville's air quality in North Carolina reflects the flat Coastal Plain terrain, with vehicle emissions from US-17 and the Camp Lejeune Marine Corps Base military vehicle and aviation training operations contributing elevated NOₓ and PM10. The surrounding North Carolina coastal plain and Onslow Bay sea breezes provide ventilation, while the flat terrain generally allows reasonable wind dispersal throughout the year.

When is air pollution at its worst in Jacksonville?
Air quality across Jacksonville rises and falls with the seasons. Typically, mild winter weather usually brings the year's cleanest air, while summer heat combined with the region's dense forest cover drives an extended ozone season. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Jacksonville 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.
