Novato's air quality benefits from the Marin County coastal valley position north of San Francisco Bay, with consistent Pacific sea breezes and the Petaluma Gap Delta breeze providing reliable maritime ventilation. Vehicle emissions from US-101 are the primary local source, while the surrounding Marin County hills and the Point Reyes peninsula create topographic variation and summer wildfire smoke from the surrounding Marin County hills is an increasingly frequent and severe seasonal concern throughout the year.

When is air pollution at its worst in Novato?
Air quality across Novato rises and falls with the seasons: the shortest stretch of clean air usually falls in the wetter winter months, but summer sunshine and heat drive some of the worst ozone readings in the country. Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.
Are air quality levels in Novato 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
