Muswellbrook's air quality is strongly influenced by the Upper Hunter's open-cut coal mining industry, a well-documented local source of particulate dust alongside more typical wood-smoke and traffic emissions. Valley topography can trap this dust and smoke on still, cold nights, particularly in winter, while summer brings the added risk of bushfire smoke from surrounding forested ranges during dry conditions. Mining-related dust monitoring is a long-standing feature of the region.

When is air pollution at its worst in Muswellbrook?
Air quality in Muswellbrook is most often challenged by dust from the Upper Hunter's open-cut coal mines, particularly on still, dry days when it combines with valley-trapped wood-smoke in winter. Summer adds bushfire smoke risk from surrounding forested country. Rain and windier weather generally provide the clearest breaks from this mining-region dust profile.
Are air quality levels in Muswellbrook 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.
