ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20140802_Methacrylolyl peroxynitrate(MPAN)/ALPHA-PINENE/hydrogen peroxide/Methacrylic acid epoxide (MAE)_Hydroxyl radical_No Seed_Dry

Abstract

Goals: This experiment is a repeat of 140724 experiment but this time with the NO2PAN monitor to quantify NO, PAN, and MPAN. The goal of this experiment is to photooxidize MPAN and capture NO3 with a-pinene, while observing secondary organic aerosol (SOA) formation through dry nucleation. MAE was added toward the end of the experiment to see if it enhanced SOA formation. Summary: Observations are the same as for 140724 - large SOA formation, alpha pinene was observed to capture NO3 which indicated that NO3 is product of MPAN oxidation, and MAE does not increase or otherwise alter SOA formation Organization: Caltech Atmospheric Chamber Lab Affiliation: California Institute of Technology, Pasadena, CA Chamber: Near/Far Bag 2012-2015 (Tran) Experiment Category: Gas phase chemical reaction, Aerosol formation Oxidant: Hydroxyl radical Reactants: Methacrylolyl peroxynitrate(MPAN), ALPHA-PINENE, hydrogen peroxide, Methacrylic acid epoxide (MAE) Reaction Type: Photooxidation Relative Humidity: 4 Temperature: 15 Pressure: 750 Torr
