Nashville's air quality reflects the Cumberland River basin's tendency to channel regional emissions, with vehicle traffic on the I-440 and I-265 beltways the primary local source in this rapidly growing southeastern US city. The surrounding Tennessee hills provide limited dispersal barriers, and summer ozone from regional and local vehicle emissions is the principal recurring warm-season concern.

When is air pollution at its worst in Nashville?
Air quality across Nashville rises and falls with the seasons — the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended, 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 Nashville 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.
