Niamey's air quality reflects the flat Niger Sahel-Sahara transition zone's Niger River valley at 227 metres, with vehicle traffic on surrounding roads and the vehicle density, motorcycle density, and construction corridor generating elevated PM2.5. Harmattan dust from the Sahara delivers catastrophic PM10 from November to March, while the extreme dust transport and dry conditions maintain Niamey among West Africa's most severely Saharan dust-challenged major Sahelian capital environments throughout the dry season.

When is air pollution at its worst in Niamey?
The biggest local contributors to pollution in Niamey are traffic on the surrounding roads, ongoing construction work, and fishing fleet activity, particularly once dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. This is most noticeable during spring and autumn wind events.
Are air quality levels in Niamey 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.
