A Study of Polar Stratospheric Clouds at the South Pole

这是一个由怀俄明大学、威斯康辛大学、NOAA/ERL/GMCC和加拿大环境部-大气环境服务局共同参与的联合项目。目的是研究平流层云的物理、化学和放射性特性，以及平流层云与每年春季南极洲上空平流层臭氧破坏之间的关系。美国国家海洋和大气管理局的工作人员将在冬末和春季从南极发射气球，放飞各种仪器。为此，一种叫做PSCsonde的新仪器被开发出来。它可以探测到PSC和平流层气溶胶，并提供一些大小分布的信息。此外，还将测量水蒸气、臭氧、温度、风、上下红外热通量，在一些飞行中还将测量硝酸蒸汽。计划在两年内进行大约40次飞行。

This is a joint project involving the University of Wyoming, the University of Wisconsin, NOAA/ERL/GMCC and Environment Canada-Atmospheric Environmental Service. The intention is to study the physical, chemical and radioactive properties of stratospheric clouds (PSC's) and the relationship between PSC's and the annual springtime destruction of stratospheric ozone over Antarctica. A variety of instruments will be flown on balloons launched from South Pole by NOAA personnel during the late winter and spring. A new instrument, called a PSCsonde, has been developed for this purpose. It can detect PSC's and stratospheric aerosols, and give some information on size distributions. In addition, measurements will be made of water vapor, ozone, temperature, winds, infrared heat flux up and down, and, on some flights, nitric acid vapor. Approximately 40 flights are planned over a two-year period.
