Point Reyes Station experiences air quality conditions shaped chiefly by cool coastal fog, and marine fog and onshore breeze keep pollutant levels low year-round. These factors combine to give Point Reyes Station a fairly typical seasonal air quality pattern for this part of the country. Visitors and residents alike tend to notice the clearest air outside the warmest summer weeks.

When is air pollution at its worst in Point Reyes Station?

Air quality across Point Reyes Station rises and falls with the seasons: the shortest stretch of clean air usually falls in the wetter winter months, but from August into October, wildfire smoke can add sharp particulate spikes on top of the usual summer ozone. The mountains ringing the basin can trap pollution close to the ground for days when winds are calm.

Are air quality levels in Point Reyes Station 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.
