Practical sea-water algorithms for fundamental bio-optical and remote sensing quantities

Abstract

Spectral in-water measurements of the downward irradiance, E _d and the upward irradiance, E _u are sufficient in order to calculate the following spectral quantities: the irradiance ratio R, the two scalar irradiances E _o and E _od, the two average cosines μ and μ _d, the light absorption coefficient a, the backscattering coefficient b _b and the vertical attenuation coefficients for the above-mentioned downward and upward irradiances. The algorithms are valid for horizontally stratified and optically deep sea waters.
