This project will make measurements of trace atmospheric gases that are important to increase our understanding of the annual antarctic ozone hole. The gases are chlorine monoxide, ozone and nitrous oxide, the first of which is a unique produce of the destruction of ozone by chlorine. Nitrous oxide is a valuable tracer of the dynamics of the atmosphere, and such measurements should be useful in determining the degree of stratospheric subsidence during the polar winter. The measurements will be made with a millimeter wavelength radio spectrometer, similar to that which has been used by this same investigator in McMurdo, Antarctica in previous years. This project is important for understanding how man-made chemicals, such as the chlorofluorocarbons, can cause global changes.

该项目将对微量大气气体进行测量，这对增加我们对南极每年的臭氧层空洞的了解非常重要。这些气体是一氧化氯、臭氧和一氧化二氮，其中第一种是氯破坏臭氧的独特产物。一氧化二氮是大气动态的宝贵示踪剂，这种测量应有助于确定极地冬季平流层下沉的程度。测量将使用毫米波长射电光谱仪，类似于前些年这位研究员在南极洲麦克默多使用的仪器。这个项目对于理解人造化学物质，如氯氟烃，如何引起全球变化很重要。
