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.

本研究的目的是研究结构和 赤道和低纬度夜间电离层的动力学。 地面光学图像将由场对准的 超赤道等离子体泡 等离子体的发射。 以前的观察表明， 底部F层的晚间扰动，随后是 它们的上升和向东漂移穿过地层。 物理 接下来要研究的过程包括最初的播种 消耗和动力，产生倾斜， 长寿命等离子体耗尽的剪切运动。
