Querétaro's air quality reflects the flat central Mexican plateau at 1,820 metres in the Querétaro valley, with vehicle traffic on surrounding roads and the aerospace manufacturing, automotive, and electronics corridor generating elevated industrial emissions. The elevated plateau position aids dispersal on most days, while winter inversions create seasonal challenges and the aerospace manufacturing character makes Querétaro Mexico's most distinctively aviation industry-defined central plateau metropolitan environment throughout most of the year.

When is air pollution at its worst in Querétaro?
In Querétaro, traffic on the surrounding roads, military aviation activity, and manufacturing and food processing are the main local sources, with conditions worsening when calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Querétaro 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.
