a
Uncertainties listed for Experiment A are typical for all experiments unless otherwise noted.
b
Measured by SMPS, assuming aerosol density of 1.0. All SOA production was observed only after prior equal or greater losses of aerosol mass.
c
Calculated from PILS-waveguide absorbance and in-line TOC measurements.
d
Measured by CAPS-ssa. Abbreviations: ΔMAC365, increase in mass absorption coefficient at 365 nm; min., minimum; ΔTOC, increase in total organic carbon; (g), gas; (p), particulate.
