Guadalupe in Nuevo León reflects the greater Monterrey metropolitan area's eastern suburban corridor in the Monterrey basin, with vehicle traffic on surrounding expressways and the manufacturing, residential, and commercial character contributing local sources. The Sierra Madre Oriental's dramatic mountain enclosure creates severe topographic concentration under winter inversions, while the Monterrey metropolitan industrial background maintains moderate to elevated northeastern Mexican mountain basin readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Guadalupe right now?
On 21 July 2026, overall air quality in Guadalupe is poor. AQI is the main air quality indicator at 70.1/100. Pollution peaks around 11:00 PM (PM10: 70.1/100).
Will air quality be worse tomorrow in Guadalupe?
On 22 July 2026, air quality conditions in Guadalupe will be worse than today, with AQI forecast at very poor at 85.4/100. Pollution peaks around 10:00 PM (PM10: 85.4/100).
When is air pollution at its worst in Guadalupe?
In Guadalupe, traffic on the surrounding roads together with manufacturing and food processing are the main local sources, with conditions worsening when the surrounding valley traps air close to the ground. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Guadalupe 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.
