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.",
