Workspace Method iySurfaceFlatReflectivity

Description

This method calculates upwelling radiation for a specular flat surface
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
