Marks Park Sports Club's position on the open Highveld plateau means vehicle traffic and government, finance, and commercial operations drive most local emissions, with winter inversions occasionally trapping pollution close to the ground. Summer brings stronger winds and regular thunderstorms that generally keep particulate levels lower across the surrounding area. It's a fairly standard picture for this part of the plateau.

When is air pollution at its worst in Marks Park Sports Club?
Winter mornings bring the worst air quality for golfers at Marks Park Sports Club, as still conditions trap emissions from government, finance, and commercial operations close to the fairways. Conditions generally clear from November onward as the summer rainfall season sets in across the wider Highveld, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Marks Park Sports Club 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.
