Worst air pollution Shire of Derby-West Kimberley, today and tomorrow

On 20 September 2026, overall air quality in Shire of Derby-West Kimberley is moderate. AQI is the main air quality indicator at 47.1/100. Pollution peaks around 8:00 AM (PM2.5: 47.1/100).

On 21 September 2026, air quality conditions in Shire of Derby-West Kimberley will be similar to today, with AQI forecast at moderate at 46.3/100. Pollution peaks around 10:00 AM (PM2.5: 46.3/100).

Winter is usually when particulate matter climbs highest locally, as cold, still air holds wood smoke and heating emissions close to the ground through winter. As the weather warms, ozone tends to overtake other concerns in this area, which forms readily in strong sunlight and heat, and can spike further during wildfire smoke events.

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.
