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.

使用Arecibo天文台上升级的钾（K）激光雷达来完成对介质附近白天温度的测量。 昼夜的平均温度结构在中层下方和下方的平均温度结构由全二十四个测量结果确定，并且还确定了Arecibo中存在的主要潮汐模式。 在温度，风和密度的三个变量中确定了中层金属层中的重力波光谱。 这些参数是根据风和ISR光谱形状的同时ISR测量结果提取的，而K-LIDAR则提供了温度和谐振k发射强度的测量值。在整个昼夜形态的背景下，研究了中层中金属层的化学。
