The fluorescence properties of water-soluble organic aerosols investigated using a fluorescence excitation-emission matrix coupled with parallel factor analysis (EEM-PARAFAC) revealed that protein-like components were dominant in our marine aerosol samples, representing 69 %-91 % of the total intensity.
