ICARUS Chamber Experiment: Caltech Atmospheric Chamber_20130325_cis-beta IEPOX_None_Ammonium sulfate_DarkReactiveUptake_RH53

Goals:
This experiment was performed to assess the reactive uptake behavior of cis beta-IEPOX that was synthesized for the experiment. Different particle inorganic compositions (mainly ammonium sulfate or AS) and different particle water content were investigated. Particles are injected into the chamber as deliquesced droplets (through a wet wall denuder) and they stabilize to their equilibrium particle liquid water content depending on their hygroscopicity.

Summary:
Large organic aerosol (OA) growth was observed
