San Luis de la Paz's air quality reflects the Guanajuato northeastern Altiplano at 2,091 metres, with vehicle traffic on surrounding roads and the mining, agriculture, and services corridor contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and San Luis de la Paz generally maintains moderate Mexican northeastern Guanajuato highland plateau readings throughout most of the year.

When is air pollution at its worst in San Luis de la Paz?
Pollution in San Luis de la Paz typically rises when traffic on the surrounding roads, quarrying activity, together with agricultural burning combine, especially once weather conditions turn unfavourable. Day-to-day conditions here depend heavily on the weather. Conditions can otherwise vary considerably with the weather.
Are air quality levels in San Luis de la Paz 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.
