Greenville's air quality reflects its position in the flat eastern North Carolina coastal plain along the Tar River, with vehicle emissions from US-264 and the East Carolina University campus and hospital traffic contributing local sources. The flat terrain generally provides reasonable wind dispersal, while summer ozone from regional agricultural and vehicle sources across the broader coastal plain is the primary warm-season concern throughout the year.

When is air pollution at its worst in Greenville?
Like most US cities, Greenville sees air quality shift from season to season. In short, the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, whereas 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 Greenville 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.
