LEAD: Scientists report that the ozone layer is slowly recovering.

1. NASA satellite data indicate the layer of ozone molecules in the upper atmosphere is headed slowly back toward normal levels.

2. The layer of ozone at high altitudes acts as a natural filter, protecting people from cancer-causing UV-B from the sun.

TAG: Scientists attribute the rebound to the 1980s ban of CFC aerosol gases.
