CEDAR Postdoc: Coordinated Space-Based Observations of Equatorial Plasma Bubbles Using TIMED/Global UltraViolet Imager (GUVI) and Defense Meteorological Satellites Program (DMSP)

赤道f区等离子体耗尽以气泡的形式出现，一直延伸到上层电离层，我们对其进行了前所未有的时空覆盖采样，以揭示耗尽的起源、结构和演变。这些结构的三维特征是通过135.6 nm的多个卫星气辉观测数据的层析反演以及630.0 nm的地面图像来确定的。TIMED卫星全球紫外成像仪（GUVI）用于创建赤道电离层的大尺度图像，DMSP-16和即将发射的DMSP-17卫星上的特殊传感器紫外光谱成像仪为GUVI提供交叉波束，并在反演后提供等离子体气泡及其演变的高空间分辨率图像。在可用的地点和时间内，这种反演也包括地面图像。该项目是博士后研究的重点，有望提高我们对赤道地区GPS和无线电闪烁干扰的预测能力。

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.
