On 30 August 2026, overall air quality in Harris Township is moderate. AQI is the main air quality indicator at 40.2/100. Pollution peaks around 11:00 AM (O3: 40.2/100).

On 31 August 2026, air quality conditions in Harris Township will be better than today, with AQI forecast at fair at 31.0/100. Pollution peaks around 11:00 AM (O3: 31.0/100).

The colder months typically bring the heaviest particulate levels of the year, as reduced winter air movement lets heating emissions and wood smoke build up locally. As temperatures rise, ozone typically becomes the dominant summer issue around here, with strong sun and heat driving ozone formation, at times worsened by wildfire smoke from farther afield.

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.
