1987年在智利蓬塔阿雷纳斯进行的南极空中臭氧实验所获得的数据表明，从8月中旬到9月下旬使命结束，南极臭氧洞外的高纬度臭氧损失。因此，不仅臭氧损失的地理范围大于通常确定的化学扰动范围，而且臭氧损失的年份也比以前报告的要早。这些结果与臭氧柱的长期时间趋势相比，表明这种损失可能有人为因素。
Data taken during the 1987 Antarctic Airborne Ozone Experiment based in Punta Arenas, Chile, are used to show that from mid-August until the end of the mission in late September there was a high-latitude ozone loss outside the Antarctic ozone hole. Therefore, not only is the geographic extent of the ozone loss larger than that generally identified as chemically perturbed, but ozone is lost earlier in the year than previously reported. These results, when compared with long-term temporal trends of column ozone, indicate a possible anthropogenic component for this loss.
