ICARUS Chamber Experiment: Nguyen Group_20220715_Nitrogen Dioxide/Ammonium Sulfate/Ozone/Hydrogen Peroxide / Ocimene_Nitrate radical_Ammonium sulfate
Listed in National Center for Atmospheric Research
Goals: To quantify SOA yield and gas-phase product yields (particularly of C10 nitrooxy-hydroperoxide and other organonitrates) from humid nighttime RO2+HO2-dominated NO3-initiated chemistry of b-ocimene.
Description
Summary
The chamber was humidified, after which H2O2, NO2, and O3 were injected in the chamber and allowed to equilibrate, forming NO3 and HO2. Ammonium sulfate seed particles were injected. Then b-ocimene was injected and decayed by simultaneous reaction with ozone and NO3.

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.
