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

摘要9615198 Deshler南极上空每年的平流层臭氧洞是由氯化合物驱动的，这些氯化合物在极地冬季形成的极地平流层云层表面相互作用。 正是由于这个原因，臭氧空洞出现在南方的春天，极地地区的臭氧消耗比其他地方严重得多。 本次调查提供了详细的资料，实际云粒子和云的分布和臭氧的气球载仪器。 这些测量将提供PSC和臭氧的垂直分布、PSC颗粒的尺寸分布以及关于其组成和物理状态（液体或固体）的一些信息。 该项目通过与一名意大利调查员的合作得到加强，该调查员在麦克默多操作激光雷达系统。 该项目为气象组织/环境署平流层变化探测网络和全球变化倡议作出了贡献。 ***

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. ***
