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、中性大气和太阳风的复杂动力学和电动力学相互作用在五个具体倡议的背景下解开。首先，利用Millstone Hill的两台Fabry-Perot干涉仪和两台全天候相机的测量结果，研究了Millstone Hill非相干散射雷达（ISR）站点和法国圣桑丁站点测量的亚极光电场差异是由飞轮机制引起的假设。其次，利用ISR等离子体线和陀螺仪线测量数据实现了一种新的电子密度和温度计算技术，并利用格陵兰岛Sondrestromfjord ISR的数据进行了测试。第三，利用分子离子模型来估计ISR光谱拟合中包含的分子种群，从而改进了离子和电子温度的测定。第四，采用一种技术，对全球赤道电场进行实时测量，目的是预测f区域电离层的不规则性，统称为赤道扩展f。第五，在智利的Cerro Tololo和秘鲁的Huancayo分别安装了两台全天候摄像机，目的是利用立体视图捕捉等离子体气泡的结构和形态。
