I have a world inside a Dyson ring with a radius of ~1 AU, complete with humans, animals, plants, clouds, and Earth-like atmosphere. The ring is spinning at a particular angular speed, giving the inhabitants on the surface the experience of Earth's gravity at sea level.
How convincing is this pseudo-gravity as a substitute for real gravity for objects not directly touching the surface?
If a bird is flying a hundred meters above the surface of the ring, does it also experience the equivalent of Earth's gravity at a hundred meters above sea level? What about a thousand meters? What about ten thousand?
Is the atmosphere comparable to Earth's at that altitude when inside the ring?
