Worst air pollution Site 9, today and tomorrow

On 26 August 2026, overall air quality in Site 9 is fair. AQI is the main air quality indicator at 35.2/100. Pollution peaks around 12:00 PM (O3: 35.2/100).

On 27 August 2026, air quality conditions in Site 9 will be similar to today, with AQI forecast at fair at 30.6/100. Pollution peaks around 8:00 AM (O3: 30.6/100).

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, since summer heat and sunlight are usually enough on their own to push ozone higher here.

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.
