CEDAR: Quantification of Thermospheric Heating by Small- Scale, High-Latitude Electric Field Fluctuations

这项研究将评估电场可变性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用于确定相关的时间和空间尺度，并确定高纬度电场变化的统计特征。 这一信息将被用来确定高纬度热层中另一种能源的参数，以用于大气环流模型。 然后将使用一个热层-电离层耦合环流模型来确定这一额外能源对高层大气的化学成分、温度和动态的重要性。

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.
