Worst air pollution James Bassett School-National Trust - Willunga, today and tomorrow

On 17 September 2026, overall air quality in James Bassett School-National Trust is fair. AQI is the main air quality indicator at 36.8/100. Pollution peaks around 2:30 PM (PM2.5: 36.8/100).

On 18 September 2026, air quality conditions in James Bassett School-National Trust will be similar to today, with AQI forecast at fair at 26.7/100. Pollution peaks around 8:30 PM (NO2: 26.7/100).

This area typically sees its worst air quality during the winter season, as reduced winter air movement lets heating emissions and wood smoke build up locally. By summer, periodic bushfire smoke becomes the more pressing issue in this area, as warm, dry conditions drive both ozone formation and periodic bushfire smoke from the surrounding region.

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.
