raman [original]
The raman option includes single order rotational Raman scattering in
the calculation. The solution treats Raman as a perturbation similar to the
approaches of Vountas1998 and Spurr2008.
The raman option may only be used for spectral calculation.
The disort radiative transfer solver with a general source is needed to solve the radiative transfer equation including Raman scattering. This solver is automagically invoked when specifying the raman option. It is thus not neccessary to set the rte_solver.
The raman option is optimized with respect to speed. The optimized implementation should be just as accurate as the original version. To use the original version invode raman original. With the optional argument original each wavelength is treated individually and is thus accurate, but computationally very expensive.
Please note that while the raman option has been extensively tested and verified, it is nevertheless a new option, hence, use it with care.
