Worst air pollution Cranbrook - Columbus, today and tomorrow

On 20 September 2026, overall air quality in Cranbrook is fair. AQI is the main air quality indicator at 32.9/100. Pollution peaks around 7:00 AM (PM1: 32.9/100).

On 21 September 2026, air quality conditions in Cranbrook will be similar to today, with AQI forecast at fair at 29.5/100. Pollution peaks around 3:00 PM (NO2: 29.5/100).

Particulate levels here tend to peak during the winter months more than any other season, when winter inversions hold traffic and heating emissions in place over the city for days at a time. The warmer months shift the main air quality risk here toward ground-level ozone, as urban heat and sunlight combine with vehicle emissions, sometimes compounded by regional wildfire smoke.

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.
