In Foster Farm, the steady churn of urban traffic and commercial activity is the leading source of particulate matter locally. Nearby tree cover helps filter some of this particulate load before it settles over the neighborhood. Day-to-day readings still shift with wind direction, traffic volume, and weather conditions. Local monitoring for the wider area tends to track closely with this general pattern.

When is air pollution at its worst in Foster Farm?
Winter months routinely see the year's steepest rise in particulate matter across this urban area, as heavy heating demand and traffic emissions combine under still, cold air that traps pollutants close to the ground. Warmer months bring a different problem here: ground-level ozone, with strong sun, heat, and traffic emissions together driving ozone higher through the summer months.
Are air quality levels in Foster Farm 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.
