Dassierand lies roughly 170 km southeast of Mahikeng. Dassierand deals with the same basic air quality drivers as most Highveld towns: vehicle traffic and maize, sunflower, and grain farming 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 Dassierand?
Winter is the tricky season for air quality at Dassierand, with calm mornings letting emissions from maize, sunflower, and grain farming operations build up under a typical Highveld inversion. Once the rainy season starts around November, conditions generally improve and stay that way into early autumn. This is a familiar pattern across much of the Highveld.
Are air quality levels in Dassierand 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.
