San Andrés Cholula's air quality reflects the flat Puebla-Tlaxcala plateau at 2,120 metres adjacent to the Great Pyramid of Cholula and the Puebla metropolitan area, with vehicle traffic on surrounding roads and the tourism, university, and residential corridor contributing local sources. The plateau's topographic enclosure creates concentration under inversions, while the elevated altitude worsens ozone formation and San Andrés Cholula shares the broader Puebla metropolitan air quality challenges throughout most of the year.

When is air pollution at its worst in San Andrés Cholula?
The biggest local contributors to pollution in San Andrés Cholula are vehicle traffic together with tourism-related traffic, particularly once summer heat and strong sunlight build up. Photochemical reactions in the heat push ozone levels higher. This is far less of an issue outside the warmer months.
Are air quality levels in San Andrés Cholula 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.
