Philippolis lies roughly 160 km southwest of Bloemfontein. At Philippolis, vehicle traffic and maize, sunflower, and grain farming operations are the dominant local sources shaping air quality on the Highveld plateau. Calm winter mornings allow emissions to build up under a low inversion layer, while the arrival of summer rains and stronger winds generally restores clearer conditions. Similar patterns show up in most Highveld towns of a similar size.

When is air pollution at its worst in Philippolis?
Philippolis sees its poorest air quality on windless winter mornings, when a low temperature inversion traps local emissions and those from maize, sunflower, and grain farming operations nearby. Summer's arrival from November brings stronger winds and thunderstorms that usually restore clearer conditions for months at a time, a seasonal pattern typical of the wider Highveld plateau.
Are air quality levels in Philippolis 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.
