Meteor Radar Studies of the Mesosphere-Lower Thermosphere Using MEDAC

该提案为使用流星回波探测和收集系统（MEDAC）对中层和低热层进行流星雷达研究寻求资金。 这项工作的目标是了解长周期波浪运动，包括迁徙潮汐和非迁徙潮汐，以及它们与大规模风环流的相互作用。 这些研究将使用从赤道太平洋风廓线仪网络收集的数据，该网络已通过 MEDAC 系统得到增强，可以确定中层和低热层的风。 为了生成这项工作所需的长数据集，需要对 MEDAC 站点进行升级。 由于 MEDAC 需要使用通常未针对流星回波检测进行优化的风廓线仪，因此 PI 建议设计一种独立的新型便携式流星雷达系统。 这个新系统以及当前的系统将通过利用遗传算法的新数据分析技术进行增强。 拟议工作的最后一个方面是与阿德莱德大学建立一个合作研究项目，允许在巴克兰公园雷达上进行实验。

This proposal seeks funds for meteor radar studies of the mesosphere and lower thermosphere using a meteor echo detection and collection system (MEDAC). The objectives of the work are to provide an understanding of the long period wave motions, including the migrating and non-migrating tides, and their interaction with the large scale wind circulation. The studies will use data collected from the equatorial Pacific wind profiler network , which has been augmented with MEDAC systems that allow the determination of the winds in the mesosphere and lower thermosphere. In order to generate the long data sets necessary for this work, an upgrade of the MEDAC sites is required. Because the MEDAC requires the use of a wind profiler that is often not optimized for meteor echo detection, the PIs propose to design a new portable meteor radar system that would stand alone. This new system, as well as the current system, will be augmented with new data analysis techniques utilizing genetic algorithms. A final aspect of the proposed work is to establish a cooperative research program with the University of Adelaide allowing experiments to be done on the Buckland Park radars.
