Algiers's air quality reflects the Mediterranean coastal Algeria position on the Bay of Algiers, with vehicle traffic on surrounding roads and the vehicle density, industrial, and construction corridor generating elevated PM2.5. Consistent Mediterranean westerlies provide maritime ventilation, while windblown Saharan dust during sirocco events delivers elevated PM10 and Algiers generally maintains moderate North African Mediterranean capital readings, with better conditions than enclosed inland Maghreb cities throughout most of the year.

When is air pollution at its worst in Algiers?
Air quality in Algiers tends to be worse when traffic on the surrounding roads together with construction dust build up and dry, windy weather picks up. Dust carried on these winds adds substantially to particulate levels. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Algiers 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.
