Mars Stadium sits in Ballarat at real elevation, around 440 metres, where cool-climate winter conditions favour wood heater smoke build-up over the surrounding suburbs on calm nights, though the venue itself, being open and exposed, generally enjoys good ventilation during events. Bushfire smoke is a periodic summer risk from surrounding forested country. There is no industry nearby. Overall, background air quality at this stadium reflects the wider Ballarat district's seasonal pattern of clean summers and smoke-prone winter evenings.

When is air pollution at its worst in Mars Stadium?
Mars Stadium, given Ballarat's elevated, inland setting, tends to see its air quality affected most by winter wood-heater smoke on cold, calm nights, and by summer bushfire smoke, December to March, from the surrounding forests. Expect the clearest conditions for outdoor matches in spring and autumn.
Are air quality levels in Mars Stadium 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.
