The Adding-doubling Method
As discussed in the preceding chapter, in practice it is not always possible to obtain the multiple-scattering properties of a plane-parallel atmosphere solely by means of the method of orders of scattering. The main reason for this is the slow convergence of successive orders of scattering for optically thick atmospheres having high values of the single scattering albedo [cf. Sec. 4.2] . Since such atmospheres are frequently met in planetary and oceanographic research, an important question is how to compute their multiple-scattering matrices, especially when their single scattering is more complicated than Rayleigh scattering.
