When is air pollution at its worst in Ijams Nature Center?

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.

Are air quality levels in Ijams Nature Center 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.
