Santa Cruz Xoxocotlán's air quality reflects the Oaxaca Valley's enclosed basin at 1,533 metres adjacent to Oaxaca International Airport, with vehicle traffic on surrounding roads and the airport operations and urban residential character contributing local sources. The Sierra Madre del Sur creates significant topographic enclosure, while winter inversions in the enclosed highland valley and the aviation emissions represent the most distinctive local emission sources and Xoxocotlán generally maintains moderate Mexican southern highland valley metropolitan readings throughout most of the year.

When is air pollution at its worst in Santa Cruz Xoxocotlán?
Santa Cruz Xoxocotlán usually sees its poorest air quality when vehicle traffic, aviation activity from the nearby airport, and fishing fleet activity coincide with periods when temperature inversions set in over the valley. The bowl-like terrain here limits how quickly pollutants can escape. This tends to happen most in winter, when inversions are most common.
Are air quality levels in Santa Cruz Xoxocotlán 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.
