Meteor Radar Studies of the Mesosphere-Lower Thermosphere Using MEDAC

该提案寻求资金，用于利用流星回波探测和收集系统对中间层和低热层进行流星雷达研究。 这项工作的目标是提供一个了解的长周期波动，包括迁移和非迁移的潮汐，以及它们与大尺度风环流的相互作用。 这些研究将使用从赤道太平洋风廓线仪网络收集的数据，该网络已得到MEDAC系统的扩充，从而可以确定中间层和低热层的风。 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需要使用风廓线仪，而风廓线仪通常不适合流星回波探测，因此PI建议设计一种新的独立便携式流星雷达系统。 这一新系统以及现有系统将得到利用遗传算法的新数据分析技术的扩充。 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计划，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.
