Mossel Bay's air quality benefits from its exceptional Atlantic and Indian Ocean dual-coastal position at the Cape Agulhas transition zone, with the Cape Doctor and consistent southwesterly and southeasterly winds providing reliable maritime ventilation. Vehicle traffic on the N2 national road and the PetroSA gas-to-liquids refinery contribute local sources, while the open ocean exposure and consistent coastal winds generally maintain moderate to good readings throughout most of the year.

Are air quality levels in Mossel Bay 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.
