Bethelsdorp's air quality reflects its position in the Nelson Mandela Bay metropolitan area inland from Port Elizabeth, with vehicle traffic on the N2 and the surrounding mixed residential and light industrial character contributing local sources. The Coega Special Economic Zone's industrial complex to the northeast and the Port Elizabeth harbour to the south contribute regional background industrial emissions, while the Indian Ocean sea breezes generally provide ventilation toward the coastal urban areas on most days.

When is air pollution at its worst in Bethelsdorp?
Air quality at Bethelsdorp tends to be slightly worse during the drier winter months, when reduced rainfall allows dust and local emissions to persist longer than usual around the town. From spring onward, increasing rainfall and the region's transitional climate between the Cape and the summer-rainfall interior generally bring clearer, more consistent conditions through summer.
Are air quality levels in Bethelsdorp 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.
