iySurfaceFlatReflectivity

This method calculates upwelling radiation for a specular flat surface.

These are due to the reflection of the downgoing diffuse radiation and emission from the surface using a predefined reflectivity matrix.

This method is designed to be part of iy_surface_agenda

Important this method calculates only the reflection of the diffuse downward radiation. No direct incoming radiation is considered

Jacobian is supported only for Skin temperature
