Abstract Yeh et al. ATM-0003418This award would support the continued development of the technique of computerized ionospheric tomography through application of this technique to the analysis of phase observations of radio signals from the TRANSIT satellites by a network of radio receivers. The results of this analysis would be a collection of 2-dimensional images of the low latitude distribution of ionospheric electron density over a latitudinal swath of about 20 degrees. About 15 such images are available for each 24 hour period. These results would be examined to study the average daily behavior for a typical day in each season to establish a baseline behavior during solar minimum conditions. Images corresponding to atypical behavior relating to special events such as solar eclipses, earthquakes, volcanic eruptions would be examined and interpreted to improve the understanding of ionospheric behavior under these circumstances. All images constructed with applications of this technique would be made available through the means of Web access.

该奖项将支持计算机化电离层层析成像技术的继续发展，通过无线电接收器网络将该技术应用于分析来自TRANSIT卫星的无线电信号的相位观测。 这种分析的结果将是在大约20度的纬度范围内电离层电子密度低纬度分布的二维图像的集合。 每24小时大约有15张这样的图像。 这些结果将被检查，以研究每个季节中典型日的平均日行为，以建立太阳能极小期条件下的基线行为。 将对与日食、地震、火山爆发等特殊事件有关的非典型行为对应的图像进行检查和解释，以提高对这些情况下电离层行为的理解。 所有应用这一技术制作的图像都将通过网络访问方式提供。
