Worst air pollution Town of Rantoul, today and tomorrow

On 2 September 2026, overall air quality in Town of Rantoul is fair. AQI is the main air quality indicator at 28.3/100. Pollution peaks around 11:00 AM (O3: 28.3/100).

On 3 September 2026, air quality conditions in Town of Rantoul will be similar to today, with AQI forecast at fair at 30.2/100. Pollution peaks around 11:00 AM (O3: 30.2/100).

Air quality often dips most sharply during winter in this area, as cold, still air holds wood smoke and heating emissions close to the ground through winter. By summer, ozone becomes the more pressing issue in this area, as sunlight and heat combine to form ozone, with occasional smoke drift adding to the load. Spring and autumn tend to offer a breather, with steadier winds helping keep pollutant levels down.

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.
