Tultepec's air quality reflects Mexico City's northern metropolitan corridor in the Valley of Mexico at 2,262 metres, with vehicle traffic on surrounding roads and the fireworks manufacturing — Tultepec being Mexico's fireworks capital — and residential corridor contributing distinctive pyrotechnic chemical aerosols alongside primary vehicle sources. The fireworks industry's extraordinary periodic chemical and metallic aerosol emissions during production and celebration events represent Tultepec's most locally unique and occasionally acute air quality characteristic throughout the year.

When is air pollution at its worst in Tultepec?
In Tultepec, vehicle traffic, heavy industry such as steel, cement, or petrochemical processing, together with manufacturing activity are the main local sources, with conditions worsening when dry, windy weather picks up. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher. These episodes tend to cluster in spring and autumn.
Are air quality levels in Tultepec 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
