In The Cottages at Illinois, traffic stays fairly light here, leaving wind-blown dust from nearby fields as a bigger factor than vehicle emissions. This is partly offset by tree cover about 89 meters away, which filters out some particulate matter naturally. Day-to-day readings still shift with wind direction, traffic volume, and weather conditions.

When is air pollution at its worst in The Cottages at Illinois?
Winter is usually when particulate matter climbs highest locally, as wood and furnace heating combine with still, cold air that traps smoke close to the ground. Warmer months bring a different problem: ground-level ozone, which forms readily in strong sunlight and heat, and can spike further during wildfire smoke events. Spring and fall typically bring a welcome improvement, as milder temperatures and better wind flow clear the air.
Are air quality levels in The Cottages at Illinois 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.
