Postmasburg lies roughly 170 km west-northwest of Kimberley. Postmasburg's sparsely populated Karoo location means vehicle traffic and diamond prospecting history and stock farming are the main local pollution sources, though the region's open landscape and frequent winds usually disperse them quickly. Windblown dust remains the main occasional exception during very dry spells. It's a fairly standard picture for this part of the interior.

When is air pollution at its worst in Postmasburg?
Windblown dust during late winter and spring is the main disruption to otherwise clean air at Postmasburg, tied partly to diamond prospecting history and stock farming in the surrounding district. For most of the year, the region's remote, open setting keeps conditions consistently favourable, a seasonal pattern typical of the wider Karoo interior.
Are air quality levels in Postmasburg 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.
