APIN and HUM O3 SOA production for aging with aqueous salt experiments

Prepare Humulene ozonolysis SOA for photolysis aging experiments

600 ppb of ozone and 500 ppb of humulene were injected into a 5 m^3 smog chamber and allowed to react for 2 h. Then the SOA was collected on a filter for aging experiments.
