Ilorin's air quality reflects the flat north-central Nigeria Kwara plateau at 307 metres in the forest-savanna transition zone, with vehicle density, cotton processing, and informal industrial corridor generating elevated PM2.5. Harmattan dust from the Sahara delivers elevated PM10 from November to March, while the transition zone location creates a distinctive seasonal contrast between harmattan and wet season conditions throughout the year.

When is air pollution at its worst in Ilorin?
In Ilorin, traffic emissions is the main local source, with conditions worsening when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. These episodes tend to cluster in spring and autumn.
Are air quality levels in Ilorin 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.
