Worst air pollution Fort Snelling Unorganized Territory, today and tomorrow

On 20 September 2026, overall air quality in Fort Snelling Unorganized Territory is fair. AQI is the main air quality indicator at 22.1/100. Pollution peaks around 6:00 AM (PM2.5: 22.1/100).

On 21 September 2026, air quality conditions in Fort Snelling Unorganized Territory will be better than today, with AQI forecast at good at 18.9/100. Pollution peaks around 6:00 AM (PM2.5: 18.9/100).

Winter is usually when particulate matter climbs highest locally, when home heating emissions build up under temperature inversions common on calm winter days. Summer shifts the concern toward ground-level ozone here too, with strong sun and heat driving ozone formation, at times worsened by wildfire smoke from farther afield. 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.
