Kempton Park's air quality reflects its position in the East Rand corridor adjacent to OR Tambo International Airport, with the airport's concentrated aviation and ground support vehicle emissions generating elevated NOₓ and ultrafine particles alongside heavy vehicle traffic on the N3 and R21. Winter Highveld temperature inversions concentrate vehicle, aviation, and industrial emissions across the East Rand plateau, while the elevated 1,550-metre position aids background dispersal on the frequent windy summer days of the Gauteng thunderstorm season.

When is air pollution at its worst in Kempton Park?
Air quality at Kempton Park is most likely to dip during the dry winter months from May to August, when temperature inversions trap vehicle and household emissions close to the ground on still mornings. Conditions improve markedly once the summer rains arrive from November, as stronger winds and regular thunderstorms clear the plateau air for the rest of the season.
Are air quality levels in Kempton Park 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.
