Soledad de Graciano Sánchez's air quality reflects the flat San Luis Potosí plateau's suburban corridor adjacent to the state capital, with vehicle traffic on surrounding roads and the manufacturing, logistics, and residential character contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create seasonal challenges and the manufacturing industrial character generally maintains moderate San Luis Potosí metropolitan eastern suburban readings throughout most of the year.

When is air pollution at its worst in Soledad de Graciano Sánchez?

Pollution in Soledad de Graciano Sánchez typically rises when traffic on the surrounding roads and manufacturing activity combine, especially once dry spells bring strong winds. Dust carried on these winds adds substantially to particulate levels. These episodes tend to cluster in spring and autumn.

Are air quality levels in Soledad de Graciano Sánchez 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.
