Wonderboom lies roughly 50 km north-northeast of Johannesburg. The Highveld plateau setting around Wonderboom means vehicle traffic and government, finance, and commercial operations are never far from the air quality picture, particularly once winter's still mornings set in. From spring onward, wind and rain reliably take over the job of clearing the air. Nearby towns on the plateau tend to see similar conditions.

When is air pollution at its worst in Wonderboom?
Air quality at Wonderboom is most likely to dip during the dry winter months from May to August, when temperature inversions trap emissions from government, finance, and commercial operations close to the ground on still mornings. Conditions improve markedly once summer rains arrive from November, as stronger winds clear the plateau air, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Wonderboom 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.
