Explanation:

The ozone hole is usually measured by reduction in the total column ozone above a point on the Earth's surface.
This is normally expressed in Dobson units; abbreviated as "DU".
The most prominent decrease in ozone has been in the lower stratosphere.
The primary cause of ozone depletion is the presence of chlorine-containing source gases (primarily CFCs and related halocarbons).
These concerns led to the adoption of the Montreal Protocol in 1987, which bans the production of CFCs, halons and other ozone-depleting chemicals.
