Yuriria's air quality reflects the flat Guanajuato Bajío plateau's Yuriria Lake basin at 1,730 metres, with vehicle traffic on surrounding roads and the lake fishing, agricultural, and services corridor contributing local sources. The lake provides limited natural ventilation, while winter inversions create modest seasonal challenges and Yuriria generally maintains moderate Mexican central Bajío plateau lake basin readings throughout most of the year.

When is air pollution at its worst in Yuriria?
The biggest local contributors to pollution in Yuriria are traffic emissions, farming and agricultural processing, and port and shipping activity, particularly once the surrounding valley traps air close to the ground. Topographic enclosure in the valley lets pollution accumulate rather than clear out. The effect is strongest during the colder months, when inversions set in most often.
Are air quality levels in Yuriria 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.
