The refractive index of particulate matter suspended in seawater
is nonuniform and potentially is an indicator of composition and
origin. A method is described for determining the refractive index
distribution. The method requires the measurement of the volume
scattering function and assumes the total size distribution to be
capable of...
An exact expression for the remotely sensed reflectance (RSR, upwelling radiance divided by downwelling scalar irradiance) just beneath the surface of the ocean is derived from the equation of radiative transfer. It is shown that the RSR at a given depth in the ocean depends only on the inherent optical...
An expression for the ratio of the upwelling nadir radiance L(π, z) and the downwelling scalar irradiance Eod(Z) is derived from the following equation of radiative transfer. This expression is given by RSR(z)=[L(π, z)]/Eod(Z) = [fb(z)bb(z)]/2π[k(π, z) + c(z) – fL(z)bf(z)], where bb(z) is the backscattering coefficient, k(π, z) is...
An expression is derived for the rate at which the diffuse attenuation coefficient for vector irradiance approaches its asymptotic value in a homogeneous medium. The asymptotic approach rate is shown to be a function of boundary conditions at the surface and the asymptotic diffuse attenuation coefficient which is an inherent...
