La Piedad's air quality reflects the flat Michoacán-Guanajuato Lerma River valley at 1,719 metres, with vehicle traffic on surrounding roads and the pork processing, footwear, and agricultural corridor contributing distinctive agricultural organic aerosols alongside primary vehicle sources. The elevated plateau position aids dispersal on most days, while winter inversions create modest seasonal challenges and the pork processing operations' distinctive organic emissions represent La Piedad's most locally unique air quality contribution throughout most of the year.

When is air pollution at its worst in La Piedad?
The biggest local contributors to pollution in La Piedad are road traffic and agricultural activity, particularly once calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. This is most pronounced in winter, when inversions are more frequent.
Are air quality levels in La Piedad 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.
