Compute polarized specular land reflectance with TELSEM2.

The atlas selects the surface emissivity from the ray point’s latitude and longitude and interpolates it in frequency and incidence angle. Set max_distance to a positive angular distance in degrees to permit nearest land-cell lookup; the default requires the requested cell to exist.
