平流层臭氧在地球上的生命和生态系统中起着至关重要的作用，大量的研究集中在人类活动对臭氧的影响上。然而，像海洋云增亮（MCB）这样的对流层气候干预方法的影响以前没有被认为会达到平流层。
研究组证明了MCB也可以对平流层和对流层臭氧产生重大影响，并揭示了这种影响可能发生的过程。该结果证明了对流层和平流层之间的内在耦合，并强调需要不仅评估MCB或任何其他气候干预的潜在地表气候影响，而且还要评估它们与整个地球系统（包括中层大气）的整体相互作用。

Abstract: Stratospheric ozone plays a crucial role in life and ecosystems on Earth, with a vast amount of research focused on the effects of human activities on ozone. Yet, impacts of tropospheric climate intervention methods like marine cloud brightening (MCB) have not previously been considered to reach the stratosphere. In this study, we demonstrate that MCB can also have a significant impact on both stratospheric and tropospheric ozone, and discuss the processes via which such an influence could occur. Our results demonstrate the inherent coupling between the troposphere and the stratosphere and underscore the need to assess not just the potential surface climate impacts of MCB, or any other climate intervention, but also their holistic interaction with the whole Earth system, including the middle atmosphere.
