Observation of Trace Gases in the Antarctic Stratosphere

该项目是国家臭氧考察（NOZE-2）的重要组成部分。通过探测臭氧（O3）、一氧化二氯（ClO）和氧化二氮（N2O）等重要气体的分子微波辐射，测量了它们的平流层柱密度，并在一定程度上测量了它们的垂直剖面。作者参加了1986年NOZE-I项目，成功地测量了臭氧、ClO和N2O。他们发现，臭氧空洞内的N2O浓度非常低，这是任何用来解释臭氧消耗的模型都没有预料到的，需要重新测量。他们还成功地探测到了海拔20公里以下的大量ClO，但他们无法确定存在的数量。对于NOZE-2，该仪器将进行改进，将带宽增加一倍，试图对ClO浓度进行更定量的测量。

This project is an important part of the National Ozone Expedition (NOZE-2). The stratospheric column density, and to some extent the vertical profile, of the important gases (O3) Ozone, (ClO) Clorine Monoxide and (N2O) Nitrous Oxide are measured by detecting their molecular microwave emissions. The proposers were participants in the NOZE-I in 1986 and successfully measured ozone, ClO and N2O. Their finding that N2O was at very low concentrations inside of the ozone hole was unanticipated by any of the models that have been developed to explain the depletion of ozone, and the measurement needs to be made again. They were also successful in detecting ClO in large quantities below 20km altitude, but they were unable to determine the amount present. For NOZE-2, the instrument will be modified by doubling the bandwidth in an attempt to make a more quantitative measurement of ClO concentration.
