在1989年1月和2月进行的空中北极平流层考察期间，从美国航天局DC-8飞机上对NO2柱丰度进行了光谱测量。据发现，极涡内部和附近的平流层空气团中的NO2含量非常低，最低的NO2垂直柱丰度低于2 × 1014 cm−2，而冬季50° N以南的丰度为3 - 5 − 1015 cm−2（WMO，1985年）。
Spectroscopic measurements of column abundances of NO2 were carried out from the NASA DC-8 airplane during the Airborne Arctic Stratospheric Expedition in January and February 1989. Stratospheric airmasses inside and close to the polar vortex were found to be highly depleted of NO2 with lowest vertical column abundances of NO2 below 2 × 1014 cm−2 compared to abundances of 3 – 5 − 1015 cm−2 south of 50° N in winter (WMO, 1985).
