Lexington's air quality in Kentucky reflects the Bluegrass region's position in the Ohio Valley airshed, with vehicle emissions from I-75 and I-64 and the surrounding bourbon distillery and horse farm agricultural operations contributing the primary local sources. The gentle Kentucky Bluegrass terrain provides reasonable wind dispersal, while the broader Ohio River valley's summer ozone burden from regional and local vehicle emissions is the primary warm-season concern.

Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Lexington 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.
