                         ecosystems, information on its seasonal variability is crucial. 
                         This study assesses the use of available absorption optical 
                         indices based on in situ data to both characterize the seasonal 
                         variability of the DOM dynamics in a highly complex environment 
                         and their viability of being used for satellite remote sensing on 
                         large scale studies. The study area comprises four lakes located 
                         at the Mamirau{\'a} Sustainable Development Reserve (MSDR). 
                         Samples for the determination of coloured dissolved organic matter 
                         (CDOM) and remote sensing reflectance (Rrs) were acquired in situ. 
                         The Rrs was applied to simulate MSI visible bands and used in the 
                         proposed models. Differences between lakes were tested regarding 
                         CDOM indices. Significant difference in the average of aCDOM 
                         (440), aCDOM spectra and S275295 were found between lakes located 
                         inside the flood forest and those near the river bank. The 
                         proposed model showed that aCDOM can be used as proxy of S275295 
                         during rising water with good validation results, demonstrating 
                         the potential of Sentinel/MSI imagery data in large scale studies 
                         on the dynamics of DOM.",
