Matehuala's air quality reflects the San Luis Potosí Altiplano's flat semi-arid plateau at 1,630 metres, with vehicle traffic on surrounding roads and the silver mining legacy, agricultural, and services corridor contributing local sources. The elevated plateau position aids dispersal on most days, while windblown Chihuahuan Desert dust contributes PM10 during dry wind events and Matehuala generally maintains moderate to good northern Mexican Altiplano plateau readings throughout most of the year.

When is air pollution at its worst in Matehuala?
Air quality in Matehuala tends to be worse when traffic emissions, mining and quarrying operations, as well as agricultural burning build up and windblown dust events occur. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Such events are most common in the drier shoulder seasons.
Are air quality levels in Matehuala 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.
