The experiment you are working you way towards carrying out involves observations made over a distance parallel to the ground, close to the ground. Refraction will depend on your atmospheric conditions there, and could be different to the refractive effect from sighting from eye height skywards.

I would think refraction would be for all practical purposes identical for
both laser beams or rays from a distant celestial object.
