Air quality around Kalgoorlie is shaped heavily by its identity as Australia's premier gold-mining hub. Dust from open-pit operations, including the large Super Pit, haul roads and processing activity, is the dominant local source, alongside natural wind-blown dust from the surrounding arid landscape. Background conditions away from mining activity are typically clean, aided by low humidity and steady winds. There's minimal vegetation-driven pollution, and any smoke events are generally linked to bushfires in surrounding scrub after wetter periods rather than urban sources.

When is air pollution at its worst in Kalgoorlie?

Air quality dips are most likely on hot, windy days when dust from mining operations and haul roads combines with natural dust lifted off the surrounding Goldfields plains, a pattern that can occur in any season but is often worse during dry, windy spring and summer stretches. Expect brief but noticeable dust haze on these days rather than prolonged smog, with conditions generally improving quickly once winds calm or light rain settles the dust.

Are air quality levels in Kalgoorlie 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.
