Worst air pollution Riverwoods, today and tomorrow

On 9 August 2026, overall air quality in Riverwoods is fair. AQI is the main air quality indicator at 32.8/100. Pollution peaks around 8:00 AM (O3: 32.8/100).

On 10 August 2026, air quality conditions in Riverwoods will be similar to today, with AQI forecast at fair at 34.7/100. Pollution peaks around 9:00 AM (O3: 34.7/100).

Riverwoods typically sees its highest particulate readings in winter, when heating and traffic emissions linger under calm, cold skies. By summer, ground-level ozone becomes the bigger issue, as intense heat and sunlight drive photochemical smog. Regional wildfire smoke can occasionally push readings higher during otherwise typical summer weather. The shoulder seasons of spring and fall usually bring the year's best air quality, helped by milder weather and steadier wind.

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.

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.
