What is the difference between bottom_top and bottom_top_stag levels?

I found the interest level by PH and PHB (bottom_top levels), but the number of levels of these variables differs from others. I'm doubt if I extracted the wind (bottom_top_stag levels) data of the correct level.
WRF employs staggered grids. In the vertical direction, there are full eta levels (bottom_top_stag) and half levels (bottom_top).

bottom_top_stag = bottom_top + 1
