2000年1月和3月，在北极的NASA DC-8飞机上测量了冰粒中所含的NOy（总活性氮）。在一些飞行中，DC-8遇到了广泛的卷云。在8-12公里处观察到大量的冰粒，颗粒NOy显示出大幅增加。数据表明，覆盖卷云冰粒的NOy的量强烈依赖于温度。1998年8月至9月和1999年在热带太平洋上空对流层上部也进行了类似的测量。在北极和热带地区获得的数据表明，在215 K以上的温度下，冰对NOy的吸收非常有限。
NOy (total reactive nitrogen) contained in ice particles was measured on board the NASA DC‐8 aircraft in the Arctic in January and March 2000. During some of the flights, the DC‐8 encountered widespread cirrus clouds. Large quantities of ice particles were observed at 8–12 km and particulate NOy showed large increases. The data indicate that the amount of NOy covering the cirrus ice particles strongly depended on temperature. Similar measurements were made in the upper troposphere over the tropical Pacific Ocean in August–September 1998 and 1999. The data obtained in the Arctic and tropics show very limited uptake of NOy on ice at temperatures above 215 K.
