Tepotzotlán's air quality reflects Mexico City's northern metropolitan corridor in the Valley of Mexico at 2,282 metres, with vehicle traffic on surrounding roads and the Jesuit heritage tourism, manufacturing, and residential character contributing local sources. The Valley of Mexico's topographic trapping compounds emissions under inversions, while the elevated ridge position provides marginally better dispersal and Tepotzotlán generally maintains moderate Mexico City northern corridor readings throughout most of the year.

When is air pollution at its worst in Tepotzotlán?
Tepotzotlán usually sees its poorest air quality when traffic emissions, light manufacturing, together with tourism-related traffic coincide with periods when temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. This is most pronounced in winter, when inversions are more frequent.
Are air quality levels in Tepotzotlán 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.
