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. ***

摘要9615198 Deshler南极上方的年平流层臭氧孔是由氯化合物驱动的，氯化合物在极性冬季形成的极性平流层云的表面上相互作用。 出于这个原因，该孔出现在澳大利亚春季中，并且在极地地区的臭氧耗竭要比其他地方更为严重。 这项调查通过使用气球传播仪器提供了有关实际云颗粒以及云和臭氧的分布的详细信息。 测量结果将提供PSC和臭氧，PSC颗粒的大小分布以及有关其组成和物理状态（液体或固体）的一些信息。 通过与在麦克默多经营激光雷达系统的意大利调查员的合作来增强该项目。 该项目有助于WMO/UNEP网络检测平流层变化和全球变化计划。 ***
