DeSoto's air quality reflects the DFW metroplex's southern Dallas County corridor, with vehicle emissions from I-35E the primary local source in this major Dallas southern suburb. The flat North Texas plain provides reasonable dispersal, while the broader DFW metropolitan ozone from vehicle and Barnett Shale natural gas emissions affects the entire southern corridor and summer ozone from the dense metroplex traffic is the primary warm-season air quality concern throughout the year.

Like most US cities, DeSoto sees air quality shift from season to season. In short, the cleanest air usually comes in the milder shoulder seasons of spring and autumn, whereas the hottest summer months consistently bring the highest ozone risk statewide. Gulf Coast humidity and inland heat can each add their own seasonal pollution patterns.
Are air quality levels in DeSoto 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.
