Lesson 8. Lakes with a high concentration of humic substances
High concentrations of humic substances leads to strong absorption of light in the blue and green parts of the spectrum, so that the remaining colour is yellow/red/brownish and dark. This leads to a low signal-to-noise ratio, so that small errors, for example in the atmospheric correction might lead to relatively large errors in the retrieval of water quality parameters. This lesson gives an overview of issues that limit remote sensing of water, with a focus on the effects of high absorption.
