La Reina in Santiago reflects the Santiago metropolitan area's northeastern residential corridor adjacent to the Andean precordillera foothills, with vehicle traffic on surrounding roads and the affluent residential and commercial character contributing local sources under the Santiago basin's persistent temperature inversions. The elevated foothills position provides marginally better dispersal, while the enclosed Central Valley's topographic trapping still compounds emissions and La Reina generally maintains moderate Santiago northeastern residential readings throughout most of the year.

When is air pollution at its worst in La Reina?
Air quality in La Reina tends to be worse when traffic emissions and calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in La Reina 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.
