Radiative Transfer in Coupled Atmosphere and Ocean Systems: the Discrete Ordinate Method
For simplicity, consider a coupled atmosphere-ocean system consisting of two adjacent slabs separated by a plane, horizontal interface across which the complex refractive index changes abruptly from a value m1 ≡ n1 + in1' in the air (atmosphere) to a value m2 ≡ n2 + in2' in the ocean. The radiation field can be split into a direct and scattered (diffuse) part:
The direct part is given by
where Fs is the irradiance (normal to the beam) of the incident (solar) beam. In either of the two slabs, the diffuse radiance distribution Idiff(τ,μ,φ) can be described by the radi ...
