Abstract

Abstract

The bidirectionality of water light field is one of the error sources of the ocean color models which nowcommonly are used to retrieve pigments' concentrations. As the launching of new generation ocean color sensors, e. g. SeaWiFS, or the coming MODIS, the goal of accuracy of ocean color sensing is now much higher than that of CZCS. The original minor factors, such as the bidirectionality of water-leaving radiance, become more important for retrieving algorithms. The results are based on the three-dimensional Monte Carlo simulations, and some aspects that should be considered for in situ optical data collection and related remote sensor's calibration and validation activities, are proposed.
- Water light field distribution,
- bidirectionality of water-leaving radiance,
- three-dimensional Monte Carlo
