Shagamu's air quality reflects the flat southwestern Nigeria Ogun State position adjacent to the Lagos-Ibadan corridor, with vehicle traffic on surrounding roads and the cement manufacturing, vehicle density, and informal industrial corridor contributing elevated mineral dust PM10 alongside primary vehicle sources. The tropical wet season's convective rain provides periodic cleansing, while dry season Harmattan dust and the cement operations maintain Shagamu as one of southwestern Nigeria's more cement manufacturing-influenced urban environments.

When is air pollution at its worst in Shagamu?
Shagamu usually sees its poorest air quality when vehicle traffic, heavy industry such as steel, cement, or petrochemical processing, along with manufacturing and food processing coincide with periods when dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Such events are most common in the drier shoulder seasons.
Are air quality levels in Shagamu 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.
