Version: 20230823-020213

Goals:
This experiment was performed to study the competition between the reactions of the smallest stabilized Criegee intermediate (SCI) CH2OO with water (or water dimer) and SO2

Summary:
At ~3% RH and 15 ppb SO2, there was a bit more sulfate particle formation as seen by the AMS, but still fairly low. While SCI+H2O products are still abundant from CIMS
