Fès's air quality reflects the Moroccan Sebou River valley's partial enclosure between the Rif and Middle Atlas ranges at 410 metres, with vehicle traffic on surrounding roads and the extraordinary tanneries — Fes hosting the world's oldest leather tanning pits — vehicle density, and craft industrial corridor generating elevated PM2.5 and distinctive organic tanning chemical emissions. The valley's topographic enclosure concentrates emissions, while the tannery's extraordinary aromatic ammonia and chromium emissions represent Fes's most historically unique local air quality signature.

When is air pollution at its worst in Fès?
Air quality in Fès tends to be worse when traffic on the surrounding roads together with heavy industrial and chemical processing build up and windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. This is most noticeable during spring and autumn wind events.
Are air quality levels in Fès 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.
