Creates variables to mimic specular reflection by a (flat) surface where surface_rv_rh and surface_ev_eh is specified.

This method is similar to surfaceFlatRvRh(), but surface_ev_eh is also specified. In surfaceFlatRvRh(), ev(eh) = 1 - rv(rh). However, the reflectivity calculated by Fastem and SURFEM-Ocean is corrected by the anisotropic downward radiation. Therefore, This method is suitable for providing both emissivity and reflectivity externally.
