Florence's air quality in Alabama reflects the Tennessee River valley in the Muscle Shoals metropolitan area, with vehicle emissions from US-72 and the surrounding automotive and manufacturing corridor contributing local sources. The Tennessee Valley's tendency to trap emissions under inversions between the Cumberland Plateau and the Appalachian foothills affects the entire Shoals region, while summer ozone from regional and local vehicle emissions is the primary warm-season concern.

When is air pollution at its worst in Florence?
Like most US cities, Florence sees air quality shift from season to season — the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, whereas summer heat, humidity, and emissions from surrounding forests combine to drive ozone levels up. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Florence 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.
