Pesquería's air quality reflects the greater Monterrey metropolitan area's eastern corridor in the Sierra Madre Oriental basin adjacent to the new Kia Motors and BMW plants, with vehicle traffic on surrounding roads and the automotive manufacturing and industrial park character contributing elevated industrial emissions. The extraordinary mountain enclosure creates severe winter inversions, while the Monterrey metropolitan industrial background and the new automotive manufacturing operations maintain moderate to elevated northeastern Mexican mountain basin readings throughout most of the year.

When is air pollution at its worst in Pesquería?
The biggest local contributors to pollution in Pesquería are road traffic as well as textile and manufacturing operations, particularly once calm, stagnant conditions settle in the surrounding valley. The bowl-like terrain here limits how quickly pollutants can escape. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Pesquería 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.
