Gastonia's air quality reflects the North Carolina Piedmont's position in the Charlotte metropolitan area, with vehicle emissions from I-85 and the surrounding textile and manufacturing legacy of the former cotton mill capital contributing local sources. The gentle Piedmont terrain provides reasonable wind dispersal, while summer ozone from the broader Charlotte metropolitan vehicle emissions and upwind southeastern US industrial sources is the primary warm-season concern throughout this Gaston County industrial corridor.

When is air pollution at its worst in Gastonia?
Air quality in Gastonia shifts across the year. In short, mild winter weather usually brings the year's cleanest air, whereas hot, humid summer days bring the highest ozone risk, amplified by natural emissions from the dense surrounding forests. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Gastonia 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.
