Phoenix's South Mountain Park air quality benefits from the 16,000-acre desert mountain preserve at 727 metres, providing exceptional clean-air separation from the Phoenix metropolitan basin below. Vehicle traffic on the approach roads contributes modest local sources, while the elevated desert mountain position above the main Phoenix valley inversion layer and the outstanding Sonoran Desert wilderness setting generally maintain South Mountain Park among the Phoenix Valley's more reliably clean natural environments throughout most of the year.

Are air quality levels in South Mountain Park 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.
