In Westwood Hills, with fewer vehicles on the road, nearby cropland dust and periodic burning outweigh traffic as a pollution source. Some of this load is absorbed by vegetation roughly 473m off, acting as a modest natural filter. The surrounding area tends to follow a similar pattern, with only minor local variation.

When is air pollution at its worst in Westwood Hills?
Air quality often dips most sharply during winter in this area, as wood and furnace heating combine with still, cold air that traps smoke close to the ground. Summer heat pushes ozone to the forefront of local air quality concerns, which forms readily in strong sunlight and heat, and can spike further during wildfire smoke events.
Are air quality levels in Westwood Hills 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.
