CEDAR: Longitudinal Variations in the Upper Atmosphere and Ionosphere Derived From Radar Measurements in the American and Asian Sectors

这个为期一年的项目旨在比较高层大气和电离层中存在的纵向差异。通过使用日本的大型MU(中高层大气)雷达，PI将在个人实验和气候平均基础上与Jicamarca、Aregbo、Millstone Hill和Sondrestrom雷达的测量结果进行比较。此外，MU雷达将把电离层倾斜研究扩展到美国部分，以确定它们的纵向一致性，并确认关于它们与全球尺度动力学关系的假设。最后，这项研究涉及在京都大学开发类似的MU雷达数据数据库。

This one-year project is aimed at comparing longitudinal differences that exist in the upper atmosphere and ionosphere. Through use of the large MU (Middle and Upper atmosphere) radar in Japan, the PIs will make comparisons on both an individual- experiment and climatological-average basis against the measurements from the Jicamarca, Arecibo, Millstone Hill, and Sondrestrom radars. In addition, the MU radar will extend the ionospheric-tilt studies to the American sector to determine their longitudinal consistency and to confirm hypotheses concerning their relation with global-scale dynamics. Finally, this research involves the development of a similar data base for MU radar data at Kyoto University.
