Eleven years of Rayleigh lidar data are analyzed to reveal cyclic and long-term behavior of mesospheric temperature at the Atmospheric Lidar Observatory (ALO) at Utah State University. The temperature climatology is compared with results from other lidars (in particular the lidar at Colorado State University), from satellites (including HALOE and SABER data), from imagers using OH rotational temperature derivations, and from empirical models (MSIS-90 and CIRA86). Climatology of gravity wave Brunt-Vaisala frequencies and potential energies are also developed using the extant data, and a search is made to determine if meteorological variations appear in the lidar data after propagation from the troposphere to the mesosphere.

分析了犹他州立大学大气激光雷达观测站(ALO)11年来的瑞利激光雷达资料，揭示了中层温度的周期性和长期行为。温度气候学与其他激光雷达(特别是科罗拉多州立大学的激光雷达)、卫星(包括HALOE和SABER数据)、使用OH旋转温度导数的成像仪以及经验模型(MSIS-90和CIRA86)的结果进行了比较。利用已有的重力波Brunt-Vaisala频率和势能的气候学资料，研究了激光雷达资料从对流层传播到中间层后是否出现气象变化。
