Mansfield's air quality in Ohio reflects the flat north-central Ohio terrain, with vehicle emissions from I-71 and the surrounding manufacturing legacy contributing local sources. The flat Ohio plain provides generally good wind dispersal, while summer regional ozone from the broader Great Lakes and Ohio Valley industrial airshed is the primary warm-season concern and the surrounding Richland County agricultural landscape contributes ammonia and dust emissions throughout the year.

When is air pollution at its worst in Mansfield?
Air quality in Mansfield shifts across the year, as the cleanest stretches usually come in spring and fall, between the summer ozone season and the calmer winter pollution episodes; by contrast, 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.
Are air quality levels in Mansfield 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.
