Short summary
Our results of this study show that two humic-like C peaks and two protein-like B and T peaks were identified from CDOM using PARAFAC for investigated lakes. The average fluorescence intensity of the components differed seasonally. Components 1 and 2 exhibited strong linear correlation (R2 = 0.63). Significantly positive linear relationships, between aCDOM and Fmax, and between DOC and salinity (R2 = 0.93), were revealed.
