abstract = "Landsat 8 is the first Earth observation satellite with sufficient
radiometric and spatial resolution to allow global mapping of lake
CDOM and DOC (coloured dissolved organic matter and dissolved
organic carbon, respectively) content. Landsat 8 is a
multispectral sensor however, the number of potentially usable
band ratios, or more sophisticated indices, is limited. In order
to test the suitability of the ratio most commonly used in lake
carbon content mapping, the green-red band ratio, we carried out
fieldwork in Estonian and Brazilian lakes. Several atmospheric
correction methods were also tested in order to use image data
where the image-to-image variability due to illumination
conditions would be minimal. None of the four atmospheric
correction methods tested, produced reflectance spectra that
matched well with in situ measured reflectance. Nevertheless, the
green-red band ratio calculated from the reflectance data was in
correlation with measured CDOM values. In situ data show that
there is a strong correlation between CDOM and DOC concentrations
in Estonian and Brazilian lakes. Thus, mapping the global CDOM and
DOC content from Landsat 8 is plausible but more data from
different parts of the world are needed before decisions can be
made about the accuracy of such global estimation.",
