(a) Size-resolved aerosol water-soluble composition measurements (reported as mass fractions) for one MOUDI sample set collected between 9 February 2010 and 25 February 2010 near Hayden, Arizona. (b) Size-resolved hygroscopic growth factor (GF) measurements after re-aerosolizing a fraction of the same water-extracted samples examined in panel (a). Thermodynamic GF predictions for ammonium bisulfate (41–42) and experimental data for laboratory-generated oxalic acid (C2H2O4) particles (43) are provided at the four RHs examined for reference in panel (b).
