Right, but this difference in refractive index is between physically existing glass and air in case of fibre optic. It might be something similar with ionospheric refraction, but In case of terrestrial refraction it is supposedly difference in refractive index of different layers of air in close proximity to the earth’s surface. Which I haven’t seen documented properly yet.

Here you go. It has to do with the temperature, pressure, and humidity of the air.

Right, this is exactly what I am talking about. I haven’t yet seen properly documented instances of atmospheric terrestrial refraction where the airs temperature, pressure and humidity is precisely recorded as well as the relative placement of those different air layers. I have only seen photos of supposed terrestrial refraction, but none of the other data, everything else is purely theoretical.
