A Study of Polar Stratospheric Clouds at the South Pole

这是一个联合项目，涉及怀俄明大学、威斯康星大学、NOAA/ERL/GMCC和加拿大环境部-大气环境服务。其目的是研究平流层云(PSC)的物理、化学和辐射特性，以及PSC与南极上空平流层臭氧每年春季破坏的关系。各种仪器将在冬末和春季由NOAA人员从南极发射的气球上飞行。为此，研制了一种名为PSCSonde的新仪器。它可以探测PSC和平流层气溶胶，并提供一些关于尺寸分布的信息。此外，还将测量水蒸气、臭氧、温度、风、红外热通量的上下变化，在一些航班上还将测量硝酸蒸气。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.
