The investigators will deploy an all-sky imager to perform mesosphere temperature mapping at the Air Force's high altitude Space Surveillance facility on Maui. The Air Force and the National Science Foundation are jointly funding a campaign to study the Mesosphere and Lower Thermosphere (MALT), referred to as Maui/MALT. The investigators will participate in the Maui/MALT campaign by (1) providing unique data on gravity wave and tidal characteristics and their induced intensity and temperature perturbations, and (2) providing frequent measurements of mesospheric temperature and intensity variability at two heights. Measurements will be made over a two-year period permitting long-term, seasonal studies of the mesosphere and lower thermosphere. The long-term measurements will complement and enhance the wind and temperature measurements to be made by a coincident lidar instrument coupled to the 3.67m Advanced Electro-Optical System telescope. These studies contribute to knowledge of the dynamics and energetics of the middle atmosphere and its sensitivity to global change.

研究人员将部署一个全天空成像仪，在空军位于毛伊岛的高空空间监视设施进行中间层温度测绘。 空军和国家科学基金会正在联合资助一项研究中间层和低热层（MALT）的活动，称为Maui/MALT。 调查人员将通过以下方式参与毛伊岛/MALT活动：（1）提供关于重力波和潮汐特征及其引起的强度和温度扰动的独特数据;（2）经常测量两个高度的中间层温度和强度变化。 将在两年期间进行测量，以便对中间层和低热层进行长期的季节性研究。 长期测量将补充和加强由耦合到3.67米高级光电系统望远镜的同步激光雷达仪器进行的风和温度测量。 这些研究有助于了解中层大气的动力学和能量学及其对全球变化的敏感性。
