本文讨论了在20°N附近和40°N-70°N范围内平流层NO2的几组扩展测量结果。在高纬度地区，主要关注NO2柱丰度与30公里附近平流层准水平流型之间的关系。NO2似乎可以作为这种流动的示踪物，特别是在冬季的高纬度地区，因为与光化学重新调整的速度相比，这种流动是迅速的。当原本NO2含量较低的极地空气被输送到较低纬度时，人们观察到NO2丰度下降；由于NO2从极地夜间储存物种中释放出来的时间较长，因此观测纬度越低，下降幅度越小。对臭氧柱总丰度和100mbar流量的研究表明，它们之间的关系类似于较高海拔NO2的关系。
This paper discusses several extended sets of measurements of stratospheric NO2 near 20°N and in the region 40°N–70°N. The principal concern at high latitude is with the relation between the NO2 column abundance and quasi-horizontal flow patterns in the stratosphere near 30 km. It appears that NO2 can serve as a tracer of such flow, particularly at higher latitude in winter when the flow is rapid in comparison with the rate of photochemical readjustment. When polar air, originally low in NO2, is delivered to lower latitude, one observes a drop in NO2 abundance; the drop is less the lower the latitude of observation owing to the greater time available for NO2 to be released from the polar night storage species. A study of total ozone column abundance and the flow at 100 mbar indicates a close relation between them similar to that for NO2 at higher altitude.
