San José del Rincón Centro in Estado de México reflects the flat Toluca Basin highland position in the Mazahua indigenous territory at 2,600 metres, with very modest traffic and agricultural operations contributing minimal 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 del Rincón Centro?
San José del Rincón Centro usually sees its poorest air quality when vehicle traffic along with farming and agricultural processing coincide with periods when weather conditions turn unfavourable. Local weather patterns add further variation on top of these sources. Background emissions and local weather both play a role in day-to-day changes.
Are air quality levels in San José del Rincón Centro 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.
