Measurements of daytime temperature near the mesopause are accomplished using an upgraded Potassium (K) lidar at the Arecibo Observatory. The diurnal mean temperature structure at and just below the mesopause is determined by full twenty-four measurements, and the dominant tidal modes present at Arecibo are also determined. Gravity wave spectra in mesospheric metal layers are determined in the three variables of temperature, wind, and density. These parameters are extracted from simultaneous ISR measurements of winds and ISR spectral shape, while the K-lidar provides measurements of temperature and the resonant K emission strength. The chemistry of metallic layers in the mesosphere is investigated in the context of the full diurnal layering morphology.

在阿雷西博天文台使用升级的钾（K）激光雷达完成了中层顶附近白天温度的测量。 全日平均温度结构和中层顶以下的是由完整的24个测量，并在阿雷西博目前占主导地位的潮汐模式也被确定。 在温度、风和密度三个变量下，确定了中层金属层中的重力波谱。 这些参数是从同时ISR测量的风和ISR光谱形状中提取的，而K激光雷达提供了温度和共振K发射强度的测量。金属层在中间层的化学研究的背景下，充分的昼夜分层形态。
