Beirut's air quality reflects the Mediterranean coastal plain's narrow Metn Mountain base position at 34 metres, with vehicle traffic on surrounding roads and the extraordinary vehicle density, ageing diesel generators — Lebanon's chronic power crisis driving pervasive private generator use — and port industrial corridor generating severely elevated PM2.5. The Mediterranean provides coastal ventilation, while the extraordinary private diesel generator dependence represents Beirut's most distinctive and acute local air quality challenge throughout most of the year.

When is air pollution at its worst in Beirut?
Pollution in Beirut typically rises when road traffic and harbour and shipping traffic combine, especially once windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Onshore breezes usually help clear the air, but pollution can build up when winds are light.
Are air quality levels in Beirut 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.
