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夜间电离层的结构和动力学。通过等离子体的复合发射，地面光学图像将由场定向的换热等离子体气泡组成。以前的观测已经显示了底部F层的晚间扰动，然后它们上升并向东漂移穿过该层。随后要研究的物理过程包括耗竭的初始播种和产生长寿命等离子体耗竭的倾斜和剪切运动的动力学。
