Nezahualcóyotl's air quality reflects Mexico City's northeastern metropolitan corridor at 2,250 metres in the Valley of Mexico, with vehicle traffic on surrounding expressways and the extraordinary dense urban residential and industrial corridor generating elevated PM2.5 under persistent valley inversions. The enclosed Valley of Mexico's near-complete topographic trapping compounds emissions extensively, while the extraordinary population density maintains Nezahualcóyotl among Mexico City metropolitan area's more persistently challenged urban environments throughout the year.

When is air pollution at its worst in Nezahualcóyotl?

Are air quality levels in Nezahualcóyotl 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.
