1TIMED卫星测量得到的OH和O_2(1.27μm)夜气辉全球分布特征显示文摘为了研究OH和O2夜间气辉辐射随时间变化的全球分布特征,我们利用TIMED卫星在2002~2009年间的OH和O2气辉辐射率数据对两种夜气辉的高度变化、地方时变化和季节变化等特征进行了统计分析.结果表明,OH夜气辉比白天气辉强,O2夜气辉比白天气辉弱.赤道附近的OH夜气辉辐射强度在午夜附近达到最强,中高纬度地区的OH夜气辉辐射强度在日落之后和日出之前较强.在分点时,赤道附近的O2夜气辉辐射强度随着地方时减弱,在至点时它的地方时-纬度分布有一个低值区.对于夜气辉辐射率的高度-纬度分布,OH的分布在分点时有一个峰,位于赤道上空85 km附近,并且3月分点的峰比9月分点的强;O2的分布在分点时有三个峰,分别位于秋分半球30°附近、赤道附近和春分半球30°附近,位于赤道附近的峰高最低;两种夜气辉在至点的分布均有三个峰.两种夜气辉的辐射强度在赤道附近有明显的年变化特征和半年变化特征,半年变化的峰值和谷值分别出现在分点和至点,并且3月分点的峰值比9月分点的大,两种气辉的分布均存在南北半球不对称特征.高红 徐寄遥 陈光明 袁韡 BELETSKY A B 2011中国科学:技术科学2011,41,3:5
2Global distributions of OH and O_2 (1.27 μm) nightglow emissions observed by TIMED satellite显示文摘In order to investigate the global distributions of temporal variations of OH and O2 nightglow emissions,we statistically analyzed their variations with altitude,local time,and season,using the OH and O2 airglow emission rate data observed by the TIMED satellite between 2002 and 2009.The results indicated that the OH nightglow emission was stronger than dayglow emission and the O2 nightglow emission was weaker than dayglow emission.In the tropics,the OH nightglow intensity reached its maximum near midnight;at higher latitudes,the OH nightglow intensities after sunset and before sunrise were much strong.At the equinoxes,the O2 nightglow intensity in the tropics decreased with local time;at the solstices,the local time-latitude distribution of the O2 nightglow intensity had a valley(with weak emission).As for the altitude-latitude distributions of nightglow emission rates,the distribution for OH nightglow at the equinoxes had one peak(with strong emission)at the equator,with a peak height around 85 km;the peak for the March equinox was stronger than that for the September equinox.The distribution for O2 nightglow at the equinoxes had three peaks,lying at 30°in the spring and autumn hemispheres and at the equator,and the peak height at the equator was the lowest.The distributions for both OH and O2 nightglow emissions at the solstices had three peaks.Both nightglow intensities in the tropics had obvious annual and semi-annual variations,the peaks and valleys for semi-annual variations appeared near the equinoxes and solstices,respectively,and the peak at the March equinox was larger than that at the September equinox.The distributions of both OH and O2 nightglow intensities showed a hemispheric asymmetry.GAO Hong XU JiYao CHEN GuangMing YUAN Wei BELETSKY A.
