Southern California ozone pollution declining and changing

Authors


Abstract

Many studies have documented the decline in ozone pollution and its precursors in the Los Angeles air basin over the past several decades. Now Pollack et al. have analyzed new data from research aircraft, along with archived data from roadside monitors and ground-based instruments, to provide a synthesis of concentrations and emissions ratios of ozone, other secondary pollutants, and their precursors from 1960 to 2010.
