The complex dynamic and electrodynamic interactions of the ionosphere, neutral atmosphere, and solar wind are untangled in the context of five specific initiatives. First, the hypothesis that discrepancies between the subauroral electrics fields measured at the Millstone Hill Incoherent Scatter Radar (ISR) site and at San Santin, France is caused by a flywheel mechanism is investigated using measurements from two Fabry-Perot interferometers and two all-sky cameras at Millstone Hill. Second, a new technique to derive electron density and temperature using ISR plasma line and gyro line measurements is implemented and tested using data from the Sondrestromfjord, Greenland ISR. Third, molecular ion models are used to estimate the molecular population to be included in ISR spectral fitting, resulting in improved ion and electron temperature determination. Fourth, a technique to assemble a real-time measure of the equatorial electrical field around the globe is applied with the intention of predicting F-region ionospheric irregularities collectively known as equatorial spread-F. Fifth, two all-sky cameras are positioned at Cerro Tololo, Chile and at Huancayo, Peru for the purpose of capturing plasma bubble structure and morphology using a stereo view.

电离层、中性大气层和太阳风之间复杂的动力学和电动学相互作用在五项具体倡议的背景下得到了解决。 首先，假设在Millstone Hill非相干散射雷达（ISR）站点和法国San Sebern测量的亚极光电场之间的差异是由飞轮机制引起的，使用Millstone Hill的两台法布里-珀罗干涉仪和两台全天空相机进行测量。 其次，使用格陵兰岛Sondrestromfjord的数据实施并测试了一种使用ISR等离子体线和陀螺仪线测量来推导电子密度和温度的新技术。 第三，分子离子模型被用来估计的分子人口包括在ISR光谱拟合，从而提高离子和电子温度的测定。 第四，采用一种技术，对地球仪周围的赤道电场进行实时测量，目的是预测统称为赤道扩展F的F区电离层不规则性。 第五，在智利的托洛洛山和秘鲁的万卡约安装了两台全天空照相机，目的是利用立体视图捕捉等离子体气泡的结构和形态。
