Mesa's air quality is shaped by the Phoenix metropolitan area's Valley of the Sun basin topography, sharing Maricopa County's notorious temperature inversion problem with central Phoenix. Vehicle emissions from the dense Superstition Freeway and US-60 corridor, windblown Sonoran Desert dust contributing PM10, and summer ozone from the vast car-dependent metropolitan area are the primary recurring air quality concerns throughout the year.

When is air pollution at its worst in Mesa?
Mesa's air quality has a clear seasonal rhythm, as winter is generally the cleanest season, with cooler temperatures and less dust in the air; by contrast, summer heat drives ozone formation, and blowing dust from spring winds can push particulate levels up abruptly. Sudden haboob-style dust storms can appear with little warning during the spring wind season.
Are air quality levels in Mesa 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.
