Worst air pollution Ijams Nature Center - Knoxville, today and tomorrow

On 9 August 2026, overall air quality in Ijams Nature Center is medium. AQI is the main air quality indicator at 42.1/100. Pollution peaks around 8:00 AM (O3: 42.1/100).

On 10 August 2026, air quality conditions in Ijams Nature Center will be worse than today, with AQI forecast at fair at 36.4/100. Pollution peaks around 11:00 AM (O3: 36.4/100).

Ijams Nature Center experiences the same seasonal air quality swings as the rest of Knoxville, as once summer humidity fades, winter typically offers the most consistently clean air; 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.

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.

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.
