Matamoros in Coahuila reflects the flat Coahuila Nazas River agricultural plain, with vehicle traffic on surrounding roads and the agricultural, cotton, and services corridor contributing local sources. The flat semi-arid Chihuahuan Desert terrain allows reasonable dispersal, while winter inversions create modest seasonal challenges and Matamoros generally maintains moderate northern Mexican Coahuila agricultural plain readings throughout most of the year.

When is air pollution at its worst in Matamoros?

Background emissions and local weather both shape how conditions change from day to day. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Matamoros 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.
