Reynosa's air quality reflects the flat Tamaulipas northeastern Gulf coastal plain adjacent to McAllen Texas, with vehicle traffic on surrounding roads and the maquiladora manufacturing, natural gas extraction, and international border crossing corridor generating elevated industrial and border vehicle emissions. The flat Gulf coastal terrain allows reasonable dispersal, while the Gulf of Mexico breezes provide warm-season ventilation and the border crossing vehicle concentration and natural gas operations represent the most distinctive local emission sources throughout the year.

When is air pollution at its worst in Reynosa?
In Reynosa, vehicle traffic, energy sector operations, together with manufacturing and food processing are the main local sources, with conditions worsening when dry spells bring strong winds. These wind events can carry dust in from the surrounding arid landscape. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Reynosa 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.
