The PIs propose to estimate distributions of electrical conductivities, neutral wind profiles, and effective electric fields in the E region through radar experiments. Secondly, they will infer three energy transfer rates in individual ionospheric flux tubes, i.e. the net Poynting flux entering/leaving the top side of the tube, the Joule heating rate in the flux tube, and the energy carried into the flux tube by auroral particle precipitation. Finally, calculations will focus on statistical averages of energy transfer rates and their relative importance with respect to magnetic latitude and local time, season, geomagnetic activity, solar wind and IMF parameters, and phase of the solar cycle.

PI建议通过雷达实验估计E区的电导率、中性风廓线和有效电场的分布。 其次，他们将推断单个电离层通量管中的三个能量传递速率，即进入/离开管顶部的净坡印廷通量、通量管中的焦耳加热速率以及极光粒子沉淀带入通量管的能量。 最后，计算将侧重于能量转移率的统计平均值及其相对于磁纬度和当地时间、季节、地磁活动、太阳风和IMF参数以及太阳周期相位的相对重要性。
