- •
Acidified sulfate aerosol enhances production of SOA from isoprene ozonolysis.
- •
Isoprene ozonolysis in the presence of acidic aerosol yields 2-methyltetrols.
- •
Unique organosulfates (OSs) are characterized from isoprene ozonolysis.
- •
2-Methyltetrols and OSs may originate from heterogeneous reaction of peroxides.
- •
Isoprene ozonolysis yields on average 14% of isoprene-derived OSs in field samples.
