在1991年9月至1992年3月的北极平流层空中考察II（AASE II）期间，在北方半球平流层下部进行了活性氮（NO[sub y]）和N[sub 2]O的现场测量。作者提出了一个新的数据进行分析，并将其与1989年冬季AASE期间采取的类似数据的结果进行比较。在北方半球，N[sub 2]O和NO[sub y]呈一致的线性相关，无年际变化。偏离线性相关性的情况下进行检查和分类是由于反硝化（NO[sub y]损失）或采样空气从一个区域的光化学寿命的NO[sub y]减少。1992年冬季首次观察到后一种情况。参考文献19篇，图4，1个选项卡。
During the Airborne Arctic Stratospheric Expedition II (AASE II), September 1991 through March 1992, in situ measurements of reactive nitrogen (NO[sub y]) and N[sub 2]O were made in the Northern Hemisphere lower stratosphere. The authors present an analysis of this new data and compare it with results from similar data taken during AASE in the winter of 1989. In the Northern Hemisphere there is a consistent linear correlation of N[sub 2]O and NO[sub y] which shows no interannual variation. Cases of departure from a linear correlation are examined and classified as being due to denitrification (NO[sub y] loss) or sampling air from a region where the photochemical lifetime of NO[sub y] is decreased. The latter case was observed for the first time in the winter of 1992. 19 refs., 4 figs., 1 tab.
