Worst air pollution Coal Mining Monument - Altona, today and tomorrow

On 17 September 2026, overall air quality in Coal Mining Monument is fair. AQI is the main air quality indicator at 37.2/100. Pollution peaks around 11:00 PM (PM2.5: 37.2/100).

On 18 September 2026, air quality conditions in Coal Mining Monument will be similar to today, with AQI forecast at fair at 37.4/100. Pollution peaks around 12:00 AM (PM2.5: 37.4/100).

Winter is usually when particulate matter climbs highest locally, driven by heating season smoke that lingers under stagnant, cold winter air. Warmer months bring a different problem: smoke haze from nearby bushfires, with bushfire smoke capable of pushing particulate readings well above the ozone increase from heat and sun alone. Between the winter and summer extremes, spring and autumn usually bring the year's most consistently clear air.

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.
