MAUI/MALT: A Meteor Radar for Collaborative Investigations of Waves, Winds, and Temperatures in the Mesosphere Above Haleakala, Hawaii

研究人员将在夏威夷哈雷阿卡拉山顶附近的毛伊岛空间监测站部署一个流星雷达系统，以研究中间层和低热层的风和温度变化的频谱。 流星雷达提供的连续风和温度测量对于解释同时进行的气辉和激光雷达观测至关重要。 此外，流星雷达对风和温度的观测与高分辨率激光雷达对温度的测量相结合，将有可能确定风场和温度场潮汐振荡及其季节变化的特征。 流星雷达将测量必要的背景风场，以确定观察到的风移波的周期，并在解释光学仪器产生的波特性统计摘要时，评估仪器滤波在波谱风移变化的情况下的作用。 这项工作将利用钠多普勒激光雷达和流星雷达搭配使用所提供的独特机会，验证和改进新开发的流星雷达和温度测量技术。 这种新技术提供了潜在的长期连续监测温度的调查长期，年度和潮汐变化的温度场在中层顶区域。

The investigators will deploy a meteor radar system at the Maui Space Surveillance Site near the summit of Haleakala, Hawaii, to study the spectrum of wind and temperature variability in the mesosphere and lower thermosphere. Continuous wind and temperature measurements provided by the meteor radar are crucial for interpreting the simultaneous airglow and lidar observations. In addition, the meteor radar observations of winds and temperatures combined with high resolution lidar measurements of temperatures will make it possible to characterize tidal oscillations in both the wind and temperature field and their seasonal variations. The meteor radar will measure the background wind field necessary to determine the periods of wind-shifted observed waves, and assess the role of instrumental filtering in the presence of variable wind shifting of the wave spectrum when interpreting statistical summaries of wave properties produced by the optical instruments. The effort will take advantage of the unique opportunity provided by the collocation of the sodium Doppler lidar and meteor radar to validate and refine the newly developed meteor radar and temperature measurement technique. This new technique offers the potential for continuous long-term monitoring of temperatures for investigations of the secular, annual, and tidal variations of the temperature field in the mesopause region.
