Measurement of Stratospheric Chlorine Monoxide and Other Trace Gases over McMurdo Station in the Austral Spring

一氧化氯（ClO）是氯破坏平流层臭氧的产物，氯是由于氟氯化碳（CFCs）的分解而存在于平流层中的。ClO以及对南极臭氧空洞很重要的其他微量平流层气体，可以用微波接收器从地面测量，类似于射电天文学中使用的接收器。该项目将继续进行长达十年的一系列此类测量，以扩展气候学，但更重要的是，也为最近安装在新西兰斯科特基地附近的新平流层变化探测网络（NDSC） ClO微波仪器提供交叉校准。作为NASA/WMO/UNEP联合方案的一部分，NDSC的仪器正在世界各地的一些地点安装，提供尽可能多的相关信息是非常重要的，以便将来可以依靠NDSC监测平流层的健康状况。＊＊＊

Abstract 9616404 de Zafra Chlorine monoxide (ClO) is a product of the destruction of stratospheric ozone by chlorine, which is present in the stratosphere as a result of the breakdown of chlorofluorocarbons (CFCs). ClO, as well as other trace stratospheric gases which are important in the Antarctic ozone hole, can be measured from the ground by microwave receivers, similar to those used in radio astronomy. This project will continue a decade long series of such measurements in order to extend the climatology, but more importantly, to also provide a cross calibration of a new Network for the Detection of Stratospheric Change (NDSC) ClO microwave instrument which has recently been installed nearby at New Zealand's Scott Base. The NDSC instruments are being installed at a number of sites world-wide as part of a joint NASA/WMO/UNEP program and it is quite important to provide as much correlative information as possible so that the NDSC can be relied upon in the future to monitor the health of the stratosphere. ***
