San Francisco's North Beach records moderate urban air quality, with Columbus Avenue and the busy tourist and restaurant traffic generating local emissions in this beloved neighbourhood below Telegraph Hill. The hilltops of Coit Tower and Russian Hill above provide better conditions, while Bay breezes from the waterfront provide periodic ventilation improvement across the lower streets.

Wine country and inland valley locations tend to see more smoke buildup than the immediate coast.
Are air quality levels in North Beach 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.
