Nouakchott's air quality reflects the extreme flat Mauritanian Atlantic coastal Sahara Desert position at 3 metres, with vehicle traffic on surrounding roads and the vehicle density, construction, and government corridor contributing local sources. Windblown Saharan dust generates some of Africa's most extreme persistent PM10, while the Atlantic trade winds provide coastal ventilation and Nouakchott maintains among the world's most severely Saharan dust-challenged coastal capital environments with PM10 elevated throughout most of the year.

When is air pollution at its worst in Nouakchott?
In Nouakchott, vehicle traffic as well as ongoing construction work are the main local sources, with conditions worsening when dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Nouakchott 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.
