Worcester's air quality in South Africa reflects the Breede River valley's topographic enclosure between the Hex River Mountains, with vehicle traffic on the N1 and surrounding wine farming contributing dust and agricultural emissions. The Cape Doctor southeasterly periodically provides powerful ventilation, while calm conditions concentrate valley emissions significantly.

Are air quality levels in Worcester 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.
