[{"name":"graham-2023-no3-1","title":"Volatility of aerosol particles from NO\u2083 oxidation of \u03b1-pinene, isoprene and \u03b2-caryophyllene","summary":"The Nitrate Aerosol and Volatility Experiment (NArVE) aimed to study the NO\u2083-induced secondary organic aerosol (SOA) formation and evolution from three biogenic volatile organic compounds (BVOCs), namely isoprene, \u03b1-pinene and \u03b2-caryophyllene.\r\n\r\nThe volatility of aerosol particles was studied using isothermal evaporation chambers, temperature-dependent evaporation in a volatility tandem differential mobility analyzer (VTDMA), and thermal desorption in a filter inlet for gases and aerosols coupled to a chemical ionization mass spectrometer (FIGAERO-CIMS). Data from these three setups present a cohesive picture of the volatility of the SOA formed in the dark from the three biogenic precursors.\r\n\r\nFour different parameterizations for estimating the saturation vapor pressure of the oxidation products were tested for reproducing the observed evaporation in a kinetic modelling framework.
