Naucalpan de Juárez's air quality reflects Mexico City's northwestern metropolitan industrial corridor at 2,270 metres in the Valley of Mexico, with vehicle traffic on surrounding expressways and the manufacturing, pharmaceutical, and dense urban corridor generating elevated PM2.5 under persistent valley inversions. The enclosed Valley of Mexico's near-complete topographic trapping compounds emissions extensively, while the industrial and pharmaceutical character maintains Naucalpan among Mexico City metropolitan area's more persistently industrial-influenced urban environments throughout the year.

When is air pollution at its worst in Naucalpan de Juárez?
Naucalpan de Juárez usually sees its poorest air quality when traffic on the surrounding roads and light manufacturing coincide with periods when calm, stagnant conditions settle in the surrounding valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Naucalpan de Juárez 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.
