Tula de Allende's air quality reflects the Hidalgo plateau's Tula River valley at 2,040 metres adjacent to the extraordinary PEMEX Miguel Hidalgo refinery and the Tula power station complex, with vehicle traffic on surrounding roads and the combined refinery and power station generating some of Mexico's most elevated local industrial SO₂ and PM2.5. The valley's topographic enclosure creates concentration under inversions, while the industrial complex's extraordinary scale makes Tula de Allende Mexico's most distinctively combined petroleum refinery and power station-defined urban air quality environment throughout the year.

When is air pollution at its worst in Tula de Allende?
Air quality in Tula de Allende tends to be worse when traffic on the surrounding roads, steel, cement, and chemical production, as well as energy sector operations build up and calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Tula de Allende 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.
