The Cornell University Portable Radar Interferometer (CUPRI) is a 50 MHz system that has provided a wealth of data for the study of ionospheric plasma turbulence. The CUPRI data sets now include a variety of auroral and mid-latitude-E-region observations, F_region chemical release experiments, and polar mesosphere measurements. Most of our observations have been coordinated with other instrumentation to provide as full a characterization of the media being probed as possible in support of several segments of the CEDAR initiative. The proposed three year renewal will fund the continuing analysis and interpretation of these extensive data sets, the completion of an upgrade of the CUPRI digitizing sub-system to improve resolution, and the acquisition and study of three new data sets. The first new data set will be obtained from northern Scandinavia for multi-frequency study of polar mesospheric summer echoes. CUPRI will set up next to the EISCAT antennas and will provide the 3 meter component of this study. Although several papers have been recently published on PSME, it is clear that more data is needed, particularly of the type that CUPRI and EISCAT can jointly obtain. The second new data set is to be of mid-latitude E-region instabilities which are not at all understood as yet. The third set will try to reproduce the remarkable mid-latitude F-region coherent echoes seen by the MU Radar. If this latter effort is successful, then we would plan to add the power of the Arecibo incoherent scatter radar in an attempt to understand these intense turbulence upwelling regions. We plan to continue to involve students in CUPRI operations, data analysis, and data interpretation: graduate students as part of their thesis research and undergraduates as part of elective courses or project regions. *** //

康奈尔大学便携式雷达干涉仪（CUPRI）是一个50兆赫的系统，为电离层等离子体湍流的研究提供了丰富的数据。CUPRI的数据集现在包括各种极光和中纬度e区观测，F_region化学释放实验和极地中间层测量。我们的大部分观察都与其他仪器进行了协调，以尽可能全面地描述所探测的媒介，以支持CEDAR倡议的几个部分。拟议的三年续期将资助这些广泛数据集的持续分析和解释，完成CUPRI数字化子系统的升级以提高分辨率，以及三个新数据集的获取和研究。第一个新的数据集将从斯堪的纳维亚北部获得，用于极地中间层夏季回波的多频率研究。CUPRI将设置在EISCAT天线旁边，并将提供本研究的3米组件。虽然最近发表了几篇关于PSME的论文，但显然需要更多的数据，特别是CUPRI和EISCAT可以共同获得的数据。第二个新数据集是关于中纬度e区域的不稳定性，这一点目前还没有完全了解。第三组将尝试重现由MU雷达看到的显著的中纬度f区相干回波。如果后一种努力是成功的，那么我们将计划增加阿雷西博非相干散射雷达的力量，试图了解这些强烈的湍流上升流区域。我们计划继续让学生参与到CUPRI的运作、数据分析和数据解释中来：研究生作为论文研究的一部分，本科生作为选修课或项目区的一部分。*** //
