San José Villa de Allende's air quality reflects the flat Estado de México highland position at 2,580 metres in the Mazahua indigenous territory, with vehicle traffic on surrounding roads and the agricultural and services character contributing very modest local sources. The elevated highland position aids dispersal, while the Mexico City-Toluca metropolitan regional background influences the area and the indigenous agricultural character generally maintains good to moderate conditions throughout most of the year.

When is air pollution at its worst in San José Villa de Allende?
In San José Villa de Allende, traffic emissions and agricultural activity are the main local sources, with conditions worsening when still air allows pollutants to build up. Local weather patterns add further variation on top of these sources. Conditions can otherwise vary considerably with the weather.
Are air quality levels in San José Villa de Allende 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.
