利用磁层顶-极光全球探测成像仪航天器上的极紫外成像仪拍摄的地球等离子体的二维图像、磁层顶-极光全球探测成像仪无线电等离子体成像仪的现场电子密度测量值、从地球表面磁强计测量的磁力线共振频率推断的磁层质量密度测量值，和密度场沿轴向变化的模型，建立了2000年8月29日1519 UT磁层密度的计算机模型。本研究的目的是演示如何使用多个数据源构建密度模型，记录此特定模型，该模型用于超低频Pi-2振荡和等离子体层腔模的研究，描述与EUV密度反演相关的一些问题，并演示等离子体层密度的一些特征，特别是在黄昏等离子体和羽流的区域。
Using a two dimensional image of the Earth's plasmasphere taken by the Extreme Ultraviolet Imager (EUV) on the Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) spacecraft, in-situ electron density measurements from the IMAGE Radio Plasma Imager (RPI) instrument, measurements of magnetospheric mass density inferred from field line resonant frequencies measured by magnetometers on the Earth's surface, and a model for the density field aligned variation, we construct a computer model for the magnetospheric density on 29 August 2000 at 1519 UT. The purposes of this study are to demonstrate how a density model can be constructed using multiple data sources, to document this particular model, which is being used in studies of ultra low frequency Pi-2 oscillations and plasmaspheric cavity modes, to describe some of the problems involved with EUV density inversion, and to demonstrate some features of the plasmaspheric density, particularly in the region of the dusk plasmatrough and plume.
