Coquimbo's air quality benefits from its exceptional Pacific Ocean and Coquimbo Bay coastal position in the Chilean Norte Chico, with consistent Pacific Humboldt Current maritime breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the fishing port, mining, and tourism corridor contribute local sources, while the outstanding Pacific coastal exposure and the Elqui Valley's dramatic backdrop generally maintain Coquimbo among Chile's more moderately ventilated northern coastal cities throughout most of the year.

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 Coquimbo 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.
