从到达高度，南极洲，平流层NO2的地面测量与TOMS卫星总臭氧测量和高空气象资料进行了比较。观测结果显示了NO2的季节性分配效应，以及春季波浪驱动输送对NO2和O3柱的影响。我们的结论是，平流层空气出现在我们的网站在春季在低压条件下是代表冷核心的极涡，它已有效地从低纬度空气隔离。在这个核心内，影响臭氧柱量和NO2水平的光化学过程可以在没有运输效应的显著影响下进行。
Ground based measurements of stratospheric NO2 made from Arrival Heights, Antarctica, are compared with TOMS satellite total ozone measurements and upper air meteorological data. The observations show the seasonal effects of partitioning on NO2, and the influence of wave driven transport on both the NO2 and O3 column in spring. We conclude that stratospheric air appearing over our site in spring during low pressure conditions is representative of the cold core of the polar vortex, which has effectively been isolated from lower latitude air. Within this core, photochemical processes influencing the ozone column amount and NO2 levels can proceed without marked influence from transport effects.
