Knoxville's Old City air quality reflects the historic entertainment and arts district adjacent to downtown, with vehicle traffic on the surrounding Jackson Avenue and Central Street corridors contributing local sources. The Tennessee River valley's enclosure creates seasonal inversion episodes, while the neighbourhood's walkable arts character and the flat terrain allow reasonable dispersal and Old City generally maintains moderate Knoxville downtown readings throughout most of the year.

When is air pollution at its worst in Old City Knoxville?
This neighborhood in Knoxville sees air quality shift through the year, as the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended; by contrast, hot, humid summer days bring the highest ozone risk, amplified by natural emissions from the dense surrounding forests. Prescribed burns are more common in the cooler months and can add brief smoke episodes.
Are air quality levels in Old City Knoxville 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
