Brazzaville's air quality reflects the flat Congo River basin position at 320 metres adjacent to Kinshasa across the river, with vehicle traffic on surrounding roads and the charcoal burning, vehicle density, and informal industrial corridor generating elevated PM2.5 and black carbon. The equatorial climate's frequent convective rain provides periodic cleansing, while dry season biomass burning from the Congo Basin contributes regional background and Brazzaville generally maintains moderate to elevated Central African capital readings throughout most of the year.

When is air pollution at its worst in Brazzaville?
Air quality in Brazzaville tends to be worse when traffic emissions along with wood-burning stoves build up and dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Coal and wood used for winter heating add substantially to particulate levels.
Are air quality levels in Brazzaville 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.
