This study explores the mechanisms behind dust levitation. Itputs the levitation altitude at 10 cm. The study also shows why the Surveyor landers recorded a glow that can be attributed to levitating dust, but Apollo crews didn't see this phenomenon: the effect is strongest near the terminator (day/night border).
This model suggests the dust is really leaping or swarming overtop a large number of shaded regions that would exist along the lunar dusk/dawn line, called the lunar terminator.
All Apollo missions landed during the local morning, far away from the terminator.
The Apollo crew did see the phenomenon from orbit (where they would pass the terminator twice per orbit).
Here's a photo taken by the Clementine spacecraft:
More factors in why this mechanism was not reported by the lander crews:
- the amount of dust transported this way is tiny. It takes 1000 years to build a layer of dust 1 mm thick.
- the particles involved are tiny ($\mu$m scale), so you can't see the individual dust particles. You just see the accumulated effect when you look horizontally through a large area with levitating dust (as in the Clementine photo above).
You can't compare this to the dust kicked up by the astronaut's feet and the rovers: that was a much larger quantity (capable of building a 1 mm layer in seconds rather than 1000 years) and it included much larger particles that are individually visible to the naked eye.
