Tepexpan's air quality reflects Mexico City's northeastern metropolitan corridor at 2,250 metres adjacent to the famous Texcoco Lake palaeontological site where the Tepexpan Man was discovered, with vehicle traffic on surrounding roads and the industrial and residential corridor generating elevated PM2.5 under the valley's persistent inversions. The Valley of Mexico's near-complete topographic trapping compounds all emissions, while the desiccated lake bed's windblown dust contributes distinctive saline aerosols throughout most of the year.

When is air pollution at its worst in Tepexpan?
Air quality in Tepexpan tends to be worse when road traffic and the surrounding valley traps air close to the ground. The bowl-like terrain here limits how quickly pollutants can escape. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Tepexpan 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.
