Frontera in Coahuila reflects the flat Coahuila Alamos River border position adjacent to Piedras Negras, with vehicle traffic on surrounding roads and the manufacturing, agricultural, and services character contributing local sources. The flat semi-arid terrain allows reasonable dispersal, while Gulf of Mexico breezes provide warm-season ventilation and Frontera generally maintains moderate northern Mexican Coahuila corridor readings throughout most of the year.

When is air pollution at its worst in Frontera?
Air quality in Frontera tends to be worse when vehicle traffic, manufacturing activity, as well as farming and agricultural processing build up and winds are light and dispersion is poor. Local weather patterns add further variation on top of these sources. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Frontera 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.
