WebThe discrete ordinates method (DOM or -approximation) is introduced in this chapter to address the directional dependence of the intensity in the radiative transfer equation (RTE). The formulation for splitting the RTE into several directional RTEs is first presented, followed by a discussion on choosing appropriate ordinate directions. WebMar 1, 2016 · The discrete ordinates method (DOM) is widely used to solve the radiative transfer equation, often yielding satisfactory results. However, in the presence of strongly forward scattering media, this method does not generally conserve the scattering energy and the phase function asymmetry factor. Because of this, the normalization of the phase ...
