Phoenix's Tempe Town Lake air quality benefits from the Salt River artificial lake's modest water body providing limited evaporative ventilation, with vehicle traffic on Mill Avenue and the surrounding Arizona State University and commercial character contributing local sources. The Valley of the Sun's persistent temperature inversion affects all of the metropolitan basin, while the lake's open water geometry provides marginally better dispersal than the enclosed street canyons and the area generally maintains moderate Phoenix metropolitan readings.

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 Tempe Town Lake 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.
