In Bellefontaine, with fewer vehicles on the road, nearby cropland dust and periodic burning outweigh traffic as a pollution source. Green space in the area offers some natural filtering, softening the local particulate load somewhat. Daily conditions can shift noticeably depending on wind, temperature, and traffic patterns. This general baseline tends to hold across nearby areas with similar traffic and land use.

When is air pollution at its worst in Bellefontaine?
The depths of winter usually mark the low point for local air quality, when home heating emissions build up under temperature inversions common on calm winter days. Summer shifts the concern toward ground-level ozone here too, as hot, sunny days accelerate local ozone formation, occasionally compounded by drifting smoke. Spring and fall stand out as the calmest stretch for air quality, thanks to mild temperatures and steady breezes.
Are air quality levels in Bellefontaine 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.
