Yaoundé's air quality reflects the flat Cameroon equatorial forest plateau at 750 metres, with vehicle traffic on surrounding roads and the vehicle density, informal industrial, and biomass burning corridor generating elevated PM2.5 and black carbon. The tropical wet season's extraordinary rainfall provides effective periodic cleansing, while dry season Harmattan dust contributes PM10 and Yaoundé generally maintains moderate to elevated Central African forest zone capital readings throughout most of the year.

When is air pollution at its worst in Yaoundé?
Air quality in Yaoundé tends to be worse when vehicle traffic as well as residential biomass burning build up and dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. These episodes tend to cluster in spring and autumn.
Are air quality levels in Yaoundé 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.
