Ciudad Nezahualcóyotl's air quality reflects Mexico City's northeastern metropolitan corridor at 2,250 metres in the Valley of Mexico, sharing the same severe topographic enclosure and persistent valley inversions that affect the broader metropolitan area. The desiccated Texcoco Lake bed's windblown toxic dust represents a distinctive additional environmental concern, while the extraordinary urban density and the enclosed valley maintain consistently elevated metropolitan readings throughout the year.

When is air pollution at its worst in Ciudad Nezahualcóyotl?

Ciudad Nezahualcóyotl usually sees its poorest air quality when vehicle traffic coincides with periods when the surrounding valley traps air close to the ground. 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 Ciudad 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.
