Abstract
This paper presents the methodology and the results of a theoretical work aiming to evaluate the potential of sea-viewing wide field-of-view sensor (SeaWiFS) visible channels for marine parameter estimate, and to propose the relevant algorithms. A model of ocean color, briefly recalled, was used for the study. With the model, a large number of reflectance curves for different values of the input parameters (the concentrations of optically active components) were generated. The curves were then integrated over the visible channels of SeaWiFS radiometer. A regression analysis between integrated reflectances and input parameters yielded the algorithms. Results are presented for case 1 and case 1 plus 2 waters, and for various kinds of algorithms, i.e. combinations of reflectance ratios and/or reflectance logarithms, and the so-called 'hyperbolic' algorithms. The values of the correlation coefficient put in evidence the effectiveness of SeaWiFS data for the retrieval of pigment, suspended sediment and yellow substance concentrations.
