The objective of this research is to study the structure and dynamics of the equatorial and low latitude nighttime ionosphere. Ground based optical images will be made of field-aligned transequatorial plasma bubbles by means of the recombination emission of the plasma. Previous observations have shown the evening perturbations of the bottomside F-layer, followed by their rise and east ward drift through the layer. Physical processes to be followed studied include the initial seeding of depletions and the dynamics that produces the tilting and shearing motions of long-lived plasma depletions.

这项研究的目的是研究赤道和低纬度夜间电离层的结构和动力学。 基于地面的光学图像将通过等离子体的重组发射来制成现场对齐的Transequatorial等离子体气泡。 先前的观察结果表明，底边F层的傍晚扰动，其次是上层的上升和东部病房漂移。 要遵循的物理过程包括耗竭的初始播种以及产生长血浆耗竭的倾斜和剪切运动的动力学。
