Abstract While air quality in the San Joaquin Valley Air Basin (SJVAB) was never as poor as it was in the South Coast Air Basin (SOCAB), reductions in ozone (O3) and particulate matter (PM2.5) in the SJVAB have been slow compared to those in the SoCAB. These different responses in ambient air quality to similar regulatory control strategies are likely a result of different atmospheric chemistry regimes occurring in the two air basins. To improve our understanding of the chemistry in the southern SJV, and thus assess one part of the comparative question, we organized a field site in Bakersfield, CA. Here we measured a wide suite of organic molecules (hydrocarbons, oxygenates, peroxides, organic acids, aldehydes; including primary emissions and secondary oxidation products), nitrogen oxides (NO, NO2, total and speciated peroxynitrates, total organic nitrates (RONO2), HNO3), hydrogen oxides (OH, HO2), O3, CO, CO2, H2O, and meteorological parameters during CalNex 2010.
