Kumasi's air quality reflects the flat Ghanaian forest-savanna transition zone at 270 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 convective rain provides periodic cleansing, while dry season Harmattan dust from the Sahara and agricultural burning elevate PM10 and Kumasi generally maintains moderate to elevated West African forest transition capital readings throughout most of the year.

When is air pollution at its worst in Kumasi?

Kumasi usually sees its poorest air quality when road traffic, crop farming, as well as residential biomass burning coincide with periods when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. Such events are most common in the drier shoulder seasons.

Are air quality levels in Kumasi 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.
