In Situ Measurements of Polar Stratospheric Clouds Spanning the Austral Winter, and of Ozone from Late Winter to Early Spring

南极上空每年的平流层臭氧空洞是由氯化合物驱动的，氯化合物在极地冬季形成的极地平流层云表面相互作用。正是由于这个原因，臭氧洞才出现在南方的春季，而臭氧消耗在极地地区比在其他地方严重得多。这次调查利用气球载仪器提供了有关实际云粒子和云及臭氧分布的详细资料。这些测量将提供PSC和臭氧的垂直剖面，PSC颗粒的大小分布以及它们的组成和物理状态（液体或固体）的一些信息。该项目通过与一名在麦克默多操作激光雷达系统的意大利调查人员合作而得到加强。该项目对气象组织/环境规划署平流层变化探测网络和全球变化倡议作出贡献。＊＊＊

Abstract 9615198 Deshler The annual stratospheric ozone hole above Antarctica is driven by chlorine compounds which interact on the surfaces of the polar stratospheric clouds which form during the polar winter. It is for this reason that the hole appears in the austral spring and that ozone depletion is much more severe in polar regions than elsewhere. This investigation provides detailed information on the actual cloud particles and the distribution of the clouds and the ozone by using balloon borne instruments. The measurements will provide vertical profiles of both the PSCs and ozone, size distributions of the PSC particles and some information on their composition and physical state (liquid or solid). The project is enhanced by cooperation with an Italian investigator who operates a lidar system in McMurdo. The project contributes to the WMO/UNEP Network for the Detection of Stratospheric Change and the Global Change Initiative. ***
