San Diego's Mission Bay Park air quality benefits from the 4,235-acre aquatic park's exceptional coastal position between the Pacific Ocean and Mission Bay, with consistent onshore Pacific sea breezes providing powerful maritime ventilation. Vehicle traffic on Mission Bay Drive contributes modest local sources, while the extraordinary dual-water open geometry ensures outstanding maritime ventilation and Mission Bay Park generally maintains among San Diego's most reliably clean major public spaces throughout most of the year.

Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.
Are air quality levels in Mission Bay Park 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.
