6 JAN 2018：Scientists claim to have been able to show for the first time that ozone depletion is declining through direct observations of the ozone hole by a satellite instrument.

科学家们宣称通过卫星直接观察臭氧洞，第一次能够证明显示臭氧洞的消耗在逐渐下降。

Measurements from NASA’s Aura satellite are said to show that the decline in chlorine, resulting from the ban on CFCs, has resulted in about 20% less ozone depletion during the Antarctic winter than there was in 2005 – the first year that measurements of chlorine and ozone during the Antarctic winter were made.

NASA的Aura卫星测量显示南极上空氯浓度相比2005减少了20%，这是禁止CFCs的结果，这是第一年在南极的冬天测氯和臭氧的浓度。

Past studies have used statistical analyses of changes in the ozone hole’s size to argue that ozone depletion is decreasing. This study is the first to use measurements of the chemical composition inside the ozone hole to confirm that not only is ozone depletion decreasing, but that the decrease is caused by the decline in CFCs.

过去的研究采用臭氧空洞的大小的统计分析来证明臭氧层破坏在减少。这次研究是第一次直接测量臭氧空洞中的化学物组份来确定不但臭氧破坏作用在减少，而且确实是由于CFCs下降而导致的。
