作为空中北极平流层考察的一部分，美国宇航局DC-8飞机同时对一氧化氮（NO）和二氧化氮（NO2）进行了现场测量。北极对流层的氮氧化物混合比（NO + NO2）通常高于平流层，中位数分别为59和40 pptv。在平流层中，NOx与水蒸气（H2O）之间的正相关性和NOx与臭氧（O3）和NOx与总活性奇氮（NOy）之间的负相关性。NOx与NOy的比值，与NOy一起，似乎是北方纬度冬季对流层或平流层空气的一个很好的示踪剂。对流层的氮氧化物通常为气相氮氧化物的10 - 50%，而在平流层中，氮氧化物通常<10%，通常<气相氮氧化物的5%。
In situ measurements of nitric oxide (NO) and nitrogen dioxide (NO2) were made simultaneously from the NASA DC-8 aircraft as part of the Airborne Arctic Stratospheric Expedition. Mixing ratios of NOx (NO + NO2) were typically higher in the Arctic troposphere than in the stratosphere, with median values of 59 and 40 pptv, respectively. In the stratosphere, there tended to be a positive correlation between NOx and water vapor (H2O) and negative correlations between NOx and ozone (O3) and between NOx and total reactive odd-nitrogen (NOy). The ratio of NOx to NOy, in conjunction with NOy, appears to be an excellent tracer of tropospheric or stratospheric air at northern latitudes during winter. Tropospheric NOx was typically 10 to 50% of gas-phase NOy, while in the stratosphere, NOx was typically < 10%, and frequently <5% of gas-phase NOy.
