Krugersdorp's air quality reflects its position in the West Rand mining corridor west of Johannesburg, with gold mine dust from the surrounding West Rand tailings dumps contributing elevated heavy metal particulates alongside vehicle traffic on the N14 and the surrounding industrial operations. Winter Highveld temperature inversions concentrate mining dust and vehicle emissions across the plateau, while the elevated 1,700-metre position aids background dispersal on windy summer days and the legacy mine dumps represent the most distinctive local PM10 source.

When is air pollution at its worst in Krugersdorp?
At Krugersdorp, the poorest air quality usually occurs on still winter mornings from May to August, when smoke and vehicle emissions accumulate under a low temperature inversion typical of the Highveld plateau. From November onward, summer rains and afternoon winds generally restore clearer conditions that last through much of the warmer part of the year.
Are air quality levels in Krugersdorp 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.
