When is air pollution at its worst in Ferry Building / Embarcadero?
Seasonal changes shape air quality at Ferry Building / Embarcadero much as they do across San Francisco — the rainy winter months generally bring the cleanest air, as storms clear traffic and woodsmoke pollution, whereas the long dry stretch from midsummer into autumn brings both ozone and wildfire smoke risk. Dry summer conditions with virtually no rain mean pollution and smoke can linger for extended stretches once they arrive.
Are air quality levels in Ferry Building / Embarcadero 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.
