cloudbox_fieldDisortWithARTSSurface

Interface to the DISORT scattering solver (by Stamnes et al.).

As cloudbox_fieldDisort() but uses surface_rtprop_agenda.

The Lambertian surface reflection is set by surface_rtprop_agenda. If the GIN inc_angle is inside of the range [0,90], the reflection is set according to the result of surface_rtprop_agenda for this incidence angle. Otherwise (default) is to call surface_rtprop_agenda for multiple angles, to estimate the hemispheric mean value.

Some auxiliary quantities can be obtained. Auxiliary quantities are selected by disort_aux_vars and returned by disort_aux. Valid choices for auxiliary data are:

"Layer optical thickness": Matrix [f_grid, size of p_grid - 1] layer optical thickness.
"Single scattering albedo": Matrix [f_grid, size of p_grid - 1] layer single”scattering albedo.
"Direct beam": Matrix [f_grid, p_grid]. Attenuated direct at level.Zero, if no sun is present
