Bunia's air quality reflects the Democratic Republic of Congo's Ituri Province's elevated equatorial position at 1,220 metres, with vehicle traffic on surrounding roads and the gold mining, humanitarian operations, and charcoal burning corridor generating elevated mineral dust and PM2.5. The equatorial highland climate's frequent rain provides periodic cleansing, while the ongoing eastern Congo conflict's extraordinary humanitarian context and the surrounding savanna's dry season burning maintain moderate to elevated Great Lakes highland readings throughout most of the year.

When is air pollution at its worst in Bunia?
In Bunia, traffic on the surrounding roads, mining and quarrying operations, as well as wood-burning stoves are the main local sources, with conditions worsening when windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Residential heating through the colder months is a major seasonal source of particulates.
Are air quality levels in Bunia 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.
