A Rayleigh lidar system will be deployed to Maui, Hawaii, to measure absolute temperatures and relative atmospheric density throughout the stratosphere and mesosphere regions in combination with simultaneous observations of upper mesosphere and lower thermosphere winds and temperatures carried out by the U. of Illinois sodium lidar system. The 10 watts laser transmitter on loan from the Univ. of Illinois would be combined with the 3.7 m USAF-AEOS telescope located on Mt. Haleakala to achieve a power aperture product unmatched by any other Rayleigh lidar system regularly operating today. These lidar measurements would be supplemented by all sky imaging observations provided by the Univ. of Illinois OH intensity imaging system and the Utah State Univ. all sky imaging system of temperature and intensity for OH and O2 emissions. This suite of measurements would provide for focused investigations of small-scale wave propagation properties within the stratosphere and mesosphere regions. Larger scale dynamical measurements would be possible by combining these results with those from the Illinois meteor radar system.

一个瑞利激光雷达系统将被部署到夏威夷的毛伊岛，以测量整个平流层和中间层区域的绝对温度和相对大气密度，并结合由美国宇航局进行的对中间层上部和热层下部风和温度的同时观测。伊利诺伊钠激光雷达系统 从伊利诺伊大学借来的10瓦激光发射器将与位于Mt. Haleakala实现了功率孔径产品，这是当今任何其他常规运行的瑞利激光雷达系统无法比拟的。 这些激光雷达测量将由伊利诺伊大学OH强度成像系统和犹他州州立大学OH和O2排放温度和强度全天空成像系统提供的全天空成像观测结果补充。 这套测量将提供对平流层和中层区域内小尺度波传播特性的重点研究。 将这些结果与伊利诺斯州流星雷达系统的结果相结合，就有可能进行更大规模的动态测量。
