Livermore's air quality reflects the Livermore Valley's partial topographic enclosure between the Diablo Range and the Altamont Hills, with vehicle emissions from I-580 the primary local source alongside the Lawrence Livermore National Laboratory's research operations. The Altamont Pass Delta breeze provides afternoon ventilation on most summer days, while summer wildfire smoke from surrounding East Bay hills and the Diablo Range is an increasingly frequent seasonal concern.

When is air pollution at its worst in Livermore?
Livermore follows a fairly predictable seasonal air quality pattern. Typically, winter typically brings the cleanest stretch, once occasional rain clears the basin, while hot, sunny summer conditions drive persistent ozone problems, compounded by wildfire smoke risk into early autumn. Coastal breezes offer some relief compared to inland valley locations that see heavier smog buildup.
Are air quality levels in Livermore 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.
