Workspace Method surfaceFlatReflectivity
Description
Creates variables to mimic specular reflection by a (flat) surface where the reflectivity is specified. The surface is treated to be flat, and the same (amplitude) reflectivity is assumed for vertical and horisontal polarisation. This assumption results in a pure diagonal surface_rmatrix (see surface chapter in AUG). Local thermodynamic equilibrium is assumed, which corresponds to that reflectivity and emissivity add up to 1. The emission is unpolarised here.
