Summary
| Description |
At an August 1985 meeting in Prague, atmospheric scientist Pawan Bhartia presented this satellite-based image that revealed for the first time the size and magnitude of the Antarctic ozone hole. The discovery ultimately led to the 1987 Montreal Protocol, a landmark international treaty designed to phase out ozone-depleting substances. Yesterday, Sept. 16,2012, marked 25 years since the treaty was opened for signatures. NASA satellites continue to provide clear snapshots of a generally stabilized Antarctic ozone hole as it cycles toward and away from its annual maximum depth by late September or early October.
