Worst air pollution Columbia Terrace North - Peoria, today and tomorrow

On 9 August 2026, overall air quality in Columbia Terrace North is fair. AQI is the main air quality indicator at 38.1/100. Pollution peaks around 10:00 AM (O3: 38.1/100).

On 10 August 2026, air quality conditions in Columbia Terrace North will be similar to today, with AQI forecast at fair at 36.1/100. Pollution peaks around 10:00 AM (O3: 36.1/100).

Cold-season conditions typically drive the sharpest particulate increases around here, when home heating emissions build up under temperature inversions common on calm winter days. Summer heat pushes ozone to the forefront of local air quality concerns, which forms readily in strong sunlight and heat, and can spike further during wildfire smoke events. Between the winter and summer extremes, spring and fall usually bring the year's most consistently clear air.

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.
