|Abstract:||In situ autonomous systems are commonly used for the collection of measurements for the vicarious calibration of satellite data and the successive validation of derived products. However, the use of autonomous systems creates the need of assessing the quality of the large volume of collected data. Within the framework of ocean color activities, this work investigates the consistency of spectral normalized water leaving radiances taken from an above-water autonomous system installed on an oceanographic tower. The study has shown the need of addressing the problem under two different levels of inference. The first level, so called self-consistency, has demonstrated the capability of identifying spectra with a low statistical representatitivity within the data set itself. The second level, so called relative-consistency, has provided the possibility of evaluating wheatear a spectrum is consistent relatively to a reference set of quality assured data.|
