Upper-Atmospheric/Ionosphere Studies with the MU Radar

9321491奥利弗与京都大学无线电大气科学中心合作，在日本重崎利用MU(中高层大气)雷达的非相干散射技术对高层大气和电离层进行了新的研究。以前的研究主要集中在短期气候学或局部电离层波传播和倾斜的形态上。该奖项将气候学扩展到太阳周期的更好部分，这些成果将形成亚洲部门对全球电场、中性风和案例研究模型的主要贡献。新的重力波研究利用了最近在识别单个波包和测量重力波的色散关系方面的最新进展，并利用一种新的共址无源流星雷达进行同步测量。最近在雷达数据减少和分析方面取得的一些进展使其中一些研究更具可行性，所有这些研究都更具潜力。***

9321491 Oliver New studies of the upper atmosphere and ionosphere by the incoherent scatter technique with the MU (Middle and Upper atmosphere) radar in Shigaraki, Japan are conducted in collaboration with the Radio Atmospheric Science Center of Kyoto University. Prior studies have focussed largely either on short- term climatology, or on the morphology of local ionospheric wave propagation and tilts. This award extends the climatology to the better part of a solar cycle, and these results will form the primary Asian-sector contribution to global models of electric fields, neutral winds, and case studies. New gravity-wave studies exploit recent advances in identifying individual wave packets and in measuring the dispersion relation for gravity waves and simultaneous measurements with a new co-located passive meteor radar. Several recent advances in radar data reduction and analysis have made some of these studies more feasible and all of them more potentially productive. ***
