Highlights

  • PM2.5 composition differed across three periods of elevated ozone

  • Isoprene-derived organosulfates contribute substantially to secondary organic aerosol (SOA)

  • SOA tracers indicate transformations occurred via photooxidation and ozonolysis

  • SOA formation was highly sensitive to aerosol acidity and inorganic sulfate
