Yeah I would say that one could explain the picture here
Ultimately, the phenomenon is happening much much higher up in the atmosphere, so being a few kilometers closer vertically won’t make a difference; but by being further up on the ground, you could see an aurora from further away and through a lot more molecules that could scatter non-red light
Oh I think I got things confused there. I was referring to the phenomenon where the sky looks red-pinkish on evenings because the Rayleigh scattering.
