Measurement of ClO, N2O and High Altitude O3 in the 1990 Antarctic Spring Stratosphere over McMurdo Station

这是一个测量丰度和垂直剖面的项目， 几种痕量气体，这对了解 氯引起的平流层臭氧破坏。 的 测量将在南极洲的麦克默多进行， 1990年春天，当每年一度的臭氧重现时， 孔预计。 使用的仪器将测量微波 臭氧、一氧化二氮和一氧化氯的无线电辐射。 通过测量发射谱线中的总辐射， 线的宽度，量和高度轮廓两者都可以是 计算了 该仪器的一个独特之处在于它采用了 超导.绝缘.超导外差式无线电 接收器，应允许这些测量与 前所未有的敏感性。 这是一项技术， 用于这些目的。 该项目由极地项目部联合资助 和大气科学部。

This is a project to measure the abundance and vertical profiles of several trace gases that are important to understanding the chlorine induced destruction of stratospheric ozone. The measurements will be made over McMurdo, Antarctica during the austral spring of 1990, when a reoccurrence of the annual ozone hole is expected. The instrument used will measure microwave radio emission from ozone, nitrous oxide and chlorine monoxide. By measuring the total radiation in the emission lines and the widths of the lines, both the amount and height profiles can be calculated. A unique feature of the instrument is that it employs a superconducting.insulating.superconducting hetrodyne radio receiver that should allow these measurements to be made with unprecedented sensitivity. This is a technology not previously employed for these purposes. This project is jointly funded by the Division of Polar Programs and the Division of Atmospheric Sciences.
