In Orrville, humid northeastern Ohio air is the main influence on air quality, and fall ragweed season is the biggest seasonal spike here. None of this is unusual for a place with Orrville's particular geography and climate. None of this replaces checking the current forecast before heading outdoors in Orrville.

When is air pollution at its worst in Orrville?
Orrville experiences a distinct seasonal swing in air quality. Typically, a brief stretch in early autumn is often the year's cleanest, once summer ozone season fades, while the hottest, most humid summer days bring the year's worst ozone readings. Fast-moving weather systems typical of the region usually keep pollution from lingering too long.
Are air quality levels in Orrville 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.
