Salamanca's air quality reflects the flat Guanajuato Bajío plateau at 1,724 metres, with vehicle traffic on surrounding roads and the PEMEX oil refinery — Mexico's most important inland refinery — and automotive manufacturing corridor generating elevated industrial SO₂ and VOCs alongside vehicle sources. The elevated plateau position aids dispersal on most days, while the PEMEX refinery's industrial scale represents Salamanca's most distinctive local air quality contribution throughout most of the year.

When is air pollution at its worst in Salamanca?
In Salamanca, traffic on the surrounding roads, steel, cement, and chemical production, together with light manufacturing are the main local sources, with conditions worsening when windblown dust events occur. These wind events can carry dust in from the surrounding arid landscape. Such events are most common in the drier shoulder seasons.
Are air quality levels in Salamanca 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.
