It should also be noted the the refractive nature of the aetheric whirlpools will distort the light, potentially changing the apparent angle of the sun.

Then how can you know for sure that your equation will produce accurate results if you don't know for sure that the angles to the sun are correct (or even meaningful)?

Ok, I understand the trig.

but now, if the earth is flat, the messurement should give the same results for h, even if done on different places.

on the other hand, if the messurements give varying results for h when taken on different places, wouldn't that mean, that earth is round or at least curved?

if so, that is quite easy to check
