This research will assess the importance of electric field variability as an upper-atmosphere energy source. Data from incoherent scatter and satellite observations will be used to define the relevant temporal and spatial scales and to determine the statistical characteristics of high-latitude E-field variability. This information will be used to parameterize an additional energy source in the high-latitude thermosphere, for use in general circulation models. A coupled thermosphere-ionosphere general circulation model will then be used to determine the significance of this additional energy source for the chemical composition, temperature, and dynamics of the upper atmosphere.

这项研究将评估电场变化作为高层大气能源的重要性。来自非相干散射和卫星观测的数据将被用来确定相关的时间和空间尺度，并确定高纬度电磁场变率的统计特征。这些信息将被用来对高纬度热层中的另一个能量源进行参数化，以用于一般环流模式。然后将使用一个耦合的热层-电离层大气环流模式来确定这种额外的能源对高层大气的化学成分、温度和动力学的重要性。
