Radiometer Sonde Soundings at Amundsen-Scott Stations, Antarctica

关于南极上空平流层“臭氧空洞”的最新数据表明，动力和化学过程的结合是造成在南方春季发生的臭氧急剧减少的原因。虽然这些过程是复杂和相互交织的，但1986年和1987年国家臭氧考察和1987年空载南极臭氧运动最近取得的实地结果确实表明，气象和化学因素都有助于南极洲上空独特的臭氧分布。迄今为止，旨在研究这一现象的活动主要集中在调查南极大陆的化学环境，关于平流层动力学的资料很少。这个实验项目的目的是从1988年7月1日开始，每隔六天在南极洲阿蒙森-斯科特站进行20毫巴压力水平的辐射计探空探测。辐射计探空仪将测量大气中随压力变化的向上、向下和净长波辐射。各压级之间的长波辐射差即为长波辐射散度。长波辐射散度可以转换为层冷却速率。层冷却速率将有助于回答有关冬季南极上空平流层动力学的问题。辐射计探空仪将探测到平流层中可能存在的卷云。这项实验是一项初步研究，目的是了解收集到的信息是否有助于了解南极大陆春季上空“臭氧空洞”的原因和演变。

Recent data on the stratospheric "ozone hole" over the Antarctic suggests that a combination of dynamical and chemical processes are responsible for the dramatic ozone decreases which takes place during the austral spring. While the processes are complex and intertwined the recent field results obtained from the National Ozone Expeditions in 1986 and 1987 and the 1987 Airborne Antarctic Ozone campaign does suggest that both meteorological and chemical factors contribute to the unique ozone distributions over Antarctica. To date the campaigns designed to study this phenomenon have concentrated primarily on investigating the chemical environment over the Antarctic continent and very little information is available about stratospheric dynamics. This experimental project is designed to make radiometer sonde soundings at Amundsen-Scott Stations, Antarctica to pressure levels of 20 millibars at six day intervals starting 1 July 1988. The radiometer sonde will measure the upward, downward, and net long wave radiation in the atmosphere as a function of pressure. The long wave radiation differences between the pressure levels will be the long wave radiation divergence. The long wave radiation divergence can be converted to layer cooling rates. The layer cooling rates will help in answering question about the dynamics of the winter times stratosphere over Antarctic. The radiometer sonde will detect the presence of possible cirrus clouds in the stratosphere. This experiment is a preliminary study to see if the information collected is of use in understanding the causes and evolution of the "ozone hole" over the Antarctic continent during the austral spring.
