             abstract = "Optical water types (OWTs) can represent diverse ranges of 
                         Chlorophyll-a (Chl-a), total suspended matter (TSM), and colored 
                         dissolved organic matter (CDOM) concentrations, which make them 
                         extremely useful for monitoring water quality, for example, 
                         detecting eutrophic conditions or tuning remote sensing 
                         algorithms. In this study, the objective is to assess OWTs found 
                         in Brazilian waters using in situ remote sensing reflectance 
                         (Rrs), acquired for water bodies encompassing a wide range of 
                         optical characteristics. Eight OWTs are obtained based on Rrs 
                         spectral shape and magnitude, which represent different 
                         limnological characteristics of Brazilian waters. The OWT 1 is 
                         clear waters with low TSM, Chl-a, and CDOM (median (x~): TSM of 
                         2.64 g m\−3, Chl-a of 6.04 mg m\−3, and CDOM of 0.6 
                         m\−1); OWT 2 represents moderate turbid waters (TSM x~ : 
                         5.14); OWTs 3, 4, and 5 are characterized by waters with high 
                         Chl-a concentration (x~ : 33.1, 39.6, and 180.4 mg m\−3, 
                         respectively); OWT 6 is characterized with the highest CDOM 
                         concentration (x~ : 4.07 m\−1); OWTs 7 and 8 consist of 
                         waters with the highest TSM concentrations from terrestrial input 
                         (x~ : 19.55 and 93.25, respectively). Hence, those OWTs could 
                         support satellite monitoring by helping to tune algorithms and 
                         also providing wide spatialtemporal monitoring.",
