Abstract

Goals:; To quantify SOA yield and gas-phase product yields from humid ozonolysis of a-pinene, which will serve as a "control" experiment to subtract the ozonolysis contribution to the nighttime chemistry of a-pinene as measured in the experiment on 5/20/22. Summary:; The chamber was humidified, after which H2O2, and O3 were injected in the chamber and allowed to equilibrate. Ammonium sulfate seed particles were injected. Then a-pinene was injected and decayed by reaction with ozone (plus some contribution from OH). Gas phase organics were monitored by CF3O- CIMS (units: normalized counts), particle formation was monitored by SMPS, and RH, T, O3, NOx were monitored throughout. O3/NOx data sometimes require post-correction not applied here, including subtraction of an ozone interference from H2O2 (1 ppm H2O2 is detected as about 12 ppb ozone) and correction for an in-line HEPA filter (see timeline for applicable timing) that scrubs about 10% of NO2 and 45% of ozone. CIMS ran out of reagent at about 14:30. Organization: Nguyen Group; Lab Affiliation: UC Davis; Chamber: Tran's big bag of air Experiment Category: Gas phase chemical reaction, Aerosol formation; Oxidant: Ozone; Reactants: alpha-Pinene, Ammonium Sulfate, Ozone, Hydrogen Peroxide; Reaction Type: Dark oxidation; Relative Humidity: 63; Temperature: 22; Seed Name: Ammonium sulfate; Pressure: ~1 atm
