Chandler's air quality reflects the Phoenix metropolitan area's Valley of the Sun enclosed basin, sharing Maricopa County's temperature inversion problem with concentrated vehicle emissions from the Loop 202 and US-60 corridors. Windblown Sonoran Desert dust contributes PM10 episodes, while summer ozone from the vast car-dependent metropolitan area and the semiconductor manufacturing industry's VOC emissions are the primary recurring air quality concerns across this rapidly growing eastern Phoenix suburb.

When is air pollution at its worst in Chandler?
Like most US cities, Chandler sees air quality shift from season to season, as the cooler winter months typically bring the cleanest air of the year; by contrast, spring winds can kick up sudden dust storms that spike particulate levels sharply for a day or two. Sudden haboob-style dust storms can appear with little warning during the spring wind season.
Are air quality levels in Chandler 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
