Observational research with a Na wind and temperature lidar, currently located at the Maui Space Surveillance Complex (a USAF facility) on Mt. Haleakala, HI, is continued. The 3.7 m aperture lidar is the centerpiece of a suite of optical and radar instrumentation located nearby for the purpose of collaborative studies of dynamics in the mesosphere and lower thermosphere (MALT). The research focus is three-fold. The first task quantifies the gravity wave induced vertical flux of horizontal momentum including directional information relevant to ducting. The directional aspect of gravity waves is used to help determine the location of generating sources. The second task is quantification of gravity wave phase and velocity using both optical and radar measurement techniques, to detect and compare both high frequency and low frequency wave phase and wave speed. The third task is to study and quantify gravity wave induced heat and constituent fluxes in the MALT region.

目前位于夏威夷州哈雷阿卡拉山毛伊岛太空监视综合设施（美国空军设施）的 Na 风和温度激光雷达的观测研究仍在继续。 3.7 m 孔径激光雷达是附近一套光学和雷达仪器的核心，用于中间层和低热层 (MALT) 动力学的协作研究。 研究重点有三个方面。 第一项任务量化重力波引起的水平动量的垂直通量，包括与管道相关的方向信息。 重力波的方向性用于帮助确定产生源的位置。 第二项任务是使用光学和雷达测量技术量化重力波相位和速度，以检测和比较高频和低频波相位和波速。 第三项任务是研究和量化 MALT 区域重力波引起的热量和成分通量。
