Phoenix's air quality is shaped by the Valley of the Sun's bowl topography, which traps vehicle emissions and dust under frequent temperature inversions, producing some of the US's highest PM10 readings from windblown Sonoran Desert dust. Summer ozone from the vast car-dependent metro and winter inversions are the two primary recurring concerns.

When is air pollution at its worst in Phoenix?
Air quality across Phoenix rises and falls with the seasons — the calmest, cleanest stretch usually falls between late autumn and early spring, whereas summer heat drives ozone formation, and blowing dust from spring winds can push particulate levels up abruptly. Monsoon storms in July and August can either clear the air with rain or stir up dust ahead of the storm front.
Are air quality levels in Phoenix 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.
