Worst air pollution Mount Airy Forest - Cincinnati, today and tomorrow

On 20 September 2026, overall air quality in Mount Airy Forest is good. AQI is the main air quality indicator at 18.5/100. Pollution peaks around 11:00 AM (PM10: 18.5/100).

On 21 September 2026, air quality conditions in Mount Airy Forest will be similar to today, with AQI forecast at good at 19.3/100. Pollution peaks around 12:00 PM (O3: 19.3/100).

Mount Airy Forest experiences the same seasonal air quality swings as the rest of Cincinnati — between summer ozone and occasional winter inversions, spring and fall are the year's cleanest stretch, whereas summer heat waves are the main driver of poor air quality, as ozone builds under stagnant, humid conditions. Lake-effect winds can help clear the air on many days near the Great Lakes shoreline.

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.
