When ozone is formed, it serves to block energetic UV (UV-B) that other molecules don't, and acts to moderate day / night temperature swings a little bit.zone has an absorption / emission band in the range of blue, so that is how we'd see it with our eyes... were it thick enough to more than add a hint of blue to our sky.
