Tepic's air quality reflects the Nayarit plateau's Mololoa River valley enclosed basin at 920 metres, with vehicle traffic on surrounding roads and the tobacco, agricultural, and government corridor contributing local sources. The surrounding Sierra Madre Occidental creates significant topographic enclosure, while winter inversions in the enclosed mountain valley create seasonal challenges and Tepic generally maintains moderate Mexican western Sierra Madre mountain valley readings throughout most of the year.

When is air pollution at its worst in Tepic?

Air quality in Tepic tends to be worse when traffic on the surrounding roads together with crop farming build up and temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. This is most pronounced in winter, when inversions are more frequent.

Are air quality levels in Tepic 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.
