Constantia Park lies roughly 190 km north-northeast of Bloemfontein. Constantia Park's air quality reflects its position on the Highveld plateau, with vehicle traffic and maize, sunflower, and grain farming operations contributing to elevated PM2.5 at times. Winter temperature inversions can concentrate emissions close to the ground, while summer thunderstorms and stronger winds generally help clear the air across the open plateau. Conditions like these are common across much of the Highveld plateau.

When is air pollution at its worst in Constantia Park?
At Constantia Park, the poorest air quality usually occurs on still winter mornings, when smoke and emissions from maize, sunflower, and grain farming operations accumulate under a low inversion typical of the Highveld. From November, summer rains and afternoon winds generally restore clearer conditions for the rest of the year, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Constantia Park 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.
