Libreville's air quality benefits from the flat Gabonese Atlantic Estuary du Gabon coastal position, with consistent Gulf of Guinea Atlantic trade winds providing maritime ventilation. Vehicle density and port and government corridor contribute local sources, while the equatorial wet season's extraordinary rainfall provides highly effective atmospheric cleansing and Libreville generally maintains moderate to good Central African Atlantic coastal capital readings throughout most of the year.

When is air pollution at its worst in Libreville?
In Libreville, vehicle traffic as well as port and shipping activity are the main local sources, with conditions worsening when onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. Areas further inland without this ventilation tend to fare worse.
Are air quality levels in Libreville 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.
