Experimental option!!!! mc_spectral_is [wvl]
Calculate a spectrum with high spectral
resolution using an importance sampling
method.
The spectral variation of Rayleigh
scattering and molecular absorption is fully
included as well the spectral variation of
aerosol and cloud scattering and absorption
coefficients. The spectral variation of the
phase matrix is neglected, for all wavelengths
the phase matrix of the calculation wavelength
is assumed.
Use the optional argument wvl to specify calculation wavelength. If not set, the central wavelength of the selected spectral interval is used.
This method is very efficient for calculations with very high spectral resolution, e.g. simulations for trace gas retrievals, in particular when polarization is required. For more details refer to emde2011. See also mc_spectral_wvl.
