磁暴会引起热层中性成分O和N2的显著变化。 为研究热层中性成分随磁暴的变化规律, 利用TIMED卫星搭载的全球紫外成像仪探测数据, 借助AURIC完成了观测角和太阳天顶角归一化, 提出了一种热层O/N2的反演方法。 通过O/N2追踪太阳风暴的发生过程, 分析了2002年9月29日到10月4日的O/N2数据发现受磁暴影响O/N2发生衰减, 且衰减范围由极区向赤道方向延伸。

Magnetic storms usually cause significant departures of thermospheric O and N2 from their normal values. To study the effects on thermospheric neutral species caused by magnetic storms, a method to retrieve thermospheric O/N2 based on the data obtained from global ultraviolet imager on board TIMED is presented. With the help of AURIC, the normalizations of observing angles and SZAs were preformed to the measurements and a relationship between 135.6/LBHs and O/N2 was established. Finally, applying the proposed method to retrieve O/N2 during a magnetic period（29, September—4, October, 2002）, it was shown that magnetic storms could induce significant O/N2 depletion, extending from the polar regions towards the equator.
