The water-leaving radiance estimated from in-water observations is associated with uncertainties due to propagation of the subsurface signal to, and across the sea surface. In order to retrieve water-leaving radiance from above water measurements, the total signal has to be accurately corrected for surface reflection of sky and sun radiation. At present, there are a number of methods for computing water-leaving radiance from in-water and above water-measurements, However, the performance of these methods has never been evaluated on the same dataset. This work represents an attempt to resolve the discrepancies between various methods commonly used by the ocean colour community. In the comparison of the methods we use a high quality dataset of simultaneous in-water and above-water radiometric measurments collected in the North Adriatic Sea in July 98,as part of SeaWIFS Bio-Optical Algorithm Round Robin Experiment.
