Local air quality near Gurnee tracks fairly closely with traffic patterns and the mix of farmland, roads, and rooftops nearby. Grant Woods Forest Preserve and the vegetation along the Des Plaines River provide some natural buffering against local particulate matter. Local weather, especially wind and temperature, accounts for most of the daily swing in readings.

When is air pollution at its worst in Gurnee?
In Gurnee, particulate matter usually peaks in winter, driven by home heating and vehicle emissions trapped by cold, still conditions. Warmer months bring a different challenge: ozone, formed when strong sun and heat interact with local emissions. Regional wildfire smoke can occasionally push readings higher during otherwise typical summer weather. Spring and fall, with milder temperatures and steadier wind, generally offer the cleanest air of the year.
Are air quality levels in Gurnee 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.
