Modeled and measured particle growth. Modeled growth rate for the new particle formation event on April 16, 2014, using oxygenated volatile organic compounds (OVOC) measured by the time-of-flight chemical ionization mass spectrometer with iodide-adduct ionization (I-TOF-CIMS) as model input, on top of size distributions measured by a differential mobility particle sizer (DMPS)
