Long-Term Aerosol Composition Trends

Inferring production mechanisms from long-term aerosol composition data.

The San Joaquin Valley of California experiences among the worst aerosol air pollution in the U.S. With support from the California Air Resources Board, we are creating a two-year record of PM2.5 composition in Fresno, California with a new Aerosol Chemical Speciation Monitor (ACSM). This work is done in collaboration with Qi Zhang and Chris Cappa at UC Davis.
