Workspace Method surfaceFlatReflectivity
Description
Creates variables to mimic specular reflection by a (flat) surface where surface_reflectivity is specified. Works basically as surfaceFlatScalarReflectivity but is more general as also vector radiative transfer is handled. See the ARTS theory document (ATD) for details around how surface_emission is determined. In the nomenclature of ATD, surface_reflectivity gives R.
