Ionospheric Research Using the Cornell University Portable Radar Interferometer (CUPRI)

利用康奈尔大学便携式雷达干涉仪（CUPRI），研究者研究了赤道电喷流、赤道扩散- f、中纬度零星- e和中纬度扩散- f区域的等离子体不稳定性。在获得了前三个地区最近的活动数据后，研究者将继续研究它们的特征。例如，在垂直入射处观测到的i型波的多普勒频移随高度减小。如果这种变化只取决于声速，我们就会认为它会随着高度的增加而增加。研究者质疑这些特征的规律性，并将在其他日子检查这些影响和相关理论。学生们还将继续从CUPRI的操作、数据分析和数据解释实验中受益，使该项目既有效又吸引国际参与。

Using the Cornell University Portable Radar Interferometer (CUPRI), the investigator studies plasma instabilities in the equatorial electrojet, equatorial spread-F, mid-latitude sporadic-E, and mid-latitude spread-F areas. Having acquired data from recent campaigns for the first three regions, the investigator will continue to examine their features. For instance, the Doppler shift of type-I waves observed at vertical incidence decreases with height...if the shift were only dependent on the acoustic speed, we'd expect an increase with height. The investigator questions the regularity of these features, and will examine other days for these effects and relevant theories. Students also continue to benefit from experimenting with CUPRI operations, data analysis, and data interpretation, making this program both effective and attractive to international participation.
