When is air pollution at its worst in Steveston?

Steveston sees clear seasonal swings in air quality, driven in part by its historic fishing-village waterfront in Richmond. Winter rain keeps the air generally clean, while hot, still summer days can trap traffic emissions and wildfire smoke against the surrounding mountains. Because the surrounding mountains can trap air on hot days, conditions occasionally worsen more here than right on the coast.

Are air quality levels in Steveston 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.
