Tecate's air quality reflects the Baja California-California border position adjacent to the famous Tecate brewery at 510 metres, with vehicle traffic on surrounding roads and the maquiladora manufacturing, Tecate beer brewing, and border crossing corridor contributing distinctive fermentation organic aerosols alongside vehicle and industrial sources. The Pacific coastal maritime influence and the elevated plateau position provide background ventilation, while the brewery's distinctive yeast emissions and the border crossing represent Tecate's most locally unique air quality contributions throughout the year.

When is air pollution at its worst in Tecate?
In Tecate, traffic on the surrounding roads together with textile and manufacturing operations are the main local sources, with conditions worsening when dry spells bring strong winds. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. Maritime airflow normally ventilates the area well, though calmer spells let levels rise.
Are air quality levels in Tecate 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.
