Short summary
This work represents a unique analysis of 10 existing air quality network sites and meteorological sites, two AmeriFlux sites, and a radio acoustic sounding system in the Central Valley of California during five consecutive fire seasons, June through September, from 2016 to 2020. We find that the ozone production rate increases by ~ 50 % during wildfire influenced periods. Wildfire smoke also decreases the heat flux by 30 % and results in 12 % lower mixed-layer height.
