Short summary
Ambient PM2.5 in California originates from a large number of diverse sources. These sources show distinct spatial and temporal variability throughout the state. Secondary aerosols are generally the most abundant contributor to ambient PM2.5 mass, while vehicular emissions and biomass burning are the main primary sources of ambient PM2.5 in California.
