Bobo-Dioulasso's air quality reflects the flat Burkina Faso Sahel-savanna transition zone at 460 metres, with vehicle traffic on surrounding roads and the cotton processing, vehicle density, and industrial corridor generating elevated PM2.5. Harmattan dust from the Sahara delivers severe PM10 from November to March, while the dry season's extreme dust transport maintains Bobo-Dioulasso among West Africa's more persistently Saharan dust-challenged major Sahelian city environments throughout the dry season.

When is air pollution at its worst in Bobo-Dioulasso?
In Bobo-Dioulasso, road traffic along with port and shipping activity are the main local sources, with conditions worsening when dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. This is most noticeable during spring and autumn wind events.
Are air quality levels in Bobo-Dioulasso 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.
