Equatorial F-region plasma depletions that are known to appear as bubbles reaching well into the topside ionosphere are sampled with unprecedented spatial and temporal coverage to reveal the origin, structure, and evolution of the depletions. The three dimensional character of these structures are determined by tomographic inversion of multiple satellite airglow observations at 135.6 nm, along with ground based imagery at 630.0 nm. The TIMED satellite Global Ultraviolet Imager (GUVI) is used to create large scale images of the equatorial ionosphere, and the Special Sensor Ultraviolet Spectrographic Imager aboard the DMSP-16 and soon to be launched DMSP-17 satellites provide cross-beams to GUVI, and upon inversion very high spatial resolution images of plasma bubbles and their evolution. Ground-based imagery is also included in this inversions where and when available. The project is the focus of postdoctoral student, and promises to improve our ability to predict GPS and radio scintillation interference in the equatorial region.

赤道F区等离子体耗尽，是已知的，以达到顶部电离层的气泡，采样前所未有的空间和时间的覆盖范围，以揭示的起源，结构和演变的耗尽。 这些结构的三维特征是通过层析反演的多个卫星气辉观测在135.6 nm，沿着与地基图像在630.0 nm。 TIMED卫星全球紫外线成像仪用于制作赤道电离层的大比例图像，DMSP-16和即将发射的DMSP-17卫星上的特殊传感器紫外线分光成像仪为全球紫外线成像仪提供交叉光束，并在反演后提供等离子体泡及其演变的极高空间分辨率图像。 地面图像也包括在这一反演在哪里和何时可用。 该项目是博士后研究的重点，有望提高我们预测GPS和赤道地区无线电闪烁干扰的能力。
