Oran's air quality reflects the flat Algerian Mediterranean coastal position on Mers El Hadjadj Bay, with vehicle density, petrochemical, and industrial corridor generating elevated PM2.5. Consistent Mediterranean westerlies provide maritime ventilation, while windblown Saharan dust during sirocco events elevates PM10 and Oran generally maintains moderate North African Mediterranean coastal metropolitan readings throughout most of the year.

When is air pollution at its worst in Oran?
The biggest local contributors to pollution in Oran are traffic on the surrounding roads and steel, cement, and chemical production, particularly once dry, windy weather picks up. 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 Oran 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.
