Clovis' air quality reflects the San Joaquin Valley's enclosed basin position adjacent to Fresno, sharing the notorious pollution trap between the Sierra Nevada and the Coast Range. Persistent valley inversions trap all winter emissions while summer ozone from the valley's combined vehicle and agricultural sources regularly produces some of California's highest readings.

When is air pollution at its worst in Clovis?
Clovis sees air quality change through the year — winter typically brings the cleanest stretch, once occasional rain clears the basin, whereas summer and early autumn bring the highest ozone levels, and wildfire smoke can spike particulate readings sharply from August through October. The mountains ringing the basin can trap pollution close to the ground for days when winds are calm.
Are air quality levels in Clovis 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.
