As a Lake Erie island, this area benefits from near-constant lake breezes that generally keep local air quality cleaner than mainland communities nearby. The greenery along the Vermilion River and inside Mill Hollow softens the particulate load somewhat for nearby areas. Most of the daily variation comes down to shifting winds and the season's typical weather patterns.

When is air pollution at its worst in Kelleys Island?
Winter around Kelleys Island typically brings the year's highest particulate readings, as heating and traffic emissions build up under calm, cold air. Warmer months bring a different challenge: ozone, formed when strong sun and heat interact with local emissions. Ferry and seasonal tourist traffic add a modest, highly seasonal emissions bump each summer. Spring and fall, with milder temperatures and steadier wind, generally offer the cleanest air of the year.
Are air quality levels in Kelleys Island 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.
