Resumo

The equations used for ocean colour and atmospheric correction algorithms are described. Their efficiency is tested by using CZCS data controlled with in situ observations. For the high chlorophyll concentrations (C > 1 mg/m3), the algorithms are very sensitive to the absolute radiometric sensor calibration and to the knowledge of the wavelength dependence of the aerosol scattering. In this case, favourable comparisons between satellite and in situ chlorophyll concentrations are only obtained to the price of careful adjustments of the algorithm parameters on a scene basis. Plans for future ocean colour sensor should consider to attempt to remedy these problems.
