In Kojonup, with fewer vehicles on the road, nearby cropland dust and periodic burning outweigh traffic as a pollution source. Nearby trees help trap a portion of this particulate load before it spreads. The surrounding area tends to follow a similar pattern, with only minor local variation. Wind patterns on any given day can shift this picture meaningfully in either direction.

On 26 August 2026, air quality conditions in Kojonup will be better than today, with AQI forecast at good at 18.4/100. Pollution peaks around 6:00 PM (NO2: 18.4/100).

When is air pollution at its worst in Kojonup?

Winter is usually when particulate matter climbs highest locally, when wood heater use and gas heating rise just as calm, cold air traps the smoke locally. Summer heat and dry surrounding vegetation push bushfire smoke to the forefront of local air quality concerns, since summer heat and dry vegetation nearby are usually enough on their own to raise bushfire risk.

Are air quality levels in Kojonup based on measurements or forecasts?

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.

Why doesn’t the forecast always reflect wildfire impacts?

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.
