利用大气探测器E上的目视气辉实验对低纬Mg+进行了二维反演分析。在F2区域获得了作为地理位置函数的数量密度分布。这些剖面代表了北方冬季白天的太阳活动极大期条件，并揭示了在475公里高度上经常出现大量密度（50-100 cm−3）。最大密度通常出现在赤道附近的1200-1400 LT。然后，随着峰值浓度向高纬度移动，赤道密度降低。金属离子浓度的时间发展纵向差异出现在下午。这些似乎是由于纬向风和/或纵向差异的垂直离子漂移速度的重要性越来越大。
Observations of low-latitude Mg+ by the Visual Airglow Experiment on Atmosphere Explorer E were analyzed by a two-dimensional inversion technique. Number density profiles as functions of geographic position were obtained in the F2 region. The profiles represent daytime northern winter, solar maximum conditions and reveal frequent occurrences of large number densities (50–100 cm−3) at altitudes up to 475 km. Maximum densities are usually found near the equator at 1200–1400 LT. The equatorial density then decreases as the peak concentrations shift to higher latitudes. Longitudinal differences in the time development of the metal ion density appear in the afternoon. These seem to be due to the increasing importance of zonal winds and/or to longitudinal differences in the vertical ion drift velocity.
