Tepatitlán de Morelos's air quality reflects the flat Jalisco Los Altos plateau at 1,787 metres, with vehicle traffic on surrounding roads and the dairy, poultry, and food processing corridor contributing local sources. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and the dairy and food processing operations' distinctive organic aerosols represent Tepatitlán's most locally unique air quality contribution throughout most of the year.

When is air pollution at its worst in Tepatitlán de Morelos?
Air quality in Tepatitlán de Morelos tends to be worse when vehicle traffic along with light manufacturing build up and still air allows pollutants to build up. Local weather patterns add further variation on top of these sources. Local weather patterns add further day-to-day variation.
Are air quality levels in Tepatitlán de Morelos 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.
