Ellis Park Arena deals with the same basic air quality drivers as most Highveld towns: vehicle traffic and government, finance, and commercial operations, both of which matter most on calm winter mornings when a low inversion holds emissions close to the ground. Summer generally undoes this with stronger, more consistent winds. The wider Highveld region generally follows this same rough pattern.

When is air pollution at its worst in Ellis Park Arena?
Winter mornings are the tricky stretch for golfers at Ellis Park Arena, as emissions from government, finance, and commercial operations build up under a calm, cold inversion typical of the Highveld. Once the rains start around November, conditions on the course generally stay clear into early autumn. This is a familiar pattern across much of the Highveld.
Are air quality levels in Ellis Park Arena 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.
