论文摘要
证明了一种方法，用于比较通过地面和卫星方法获得的上层气氛的温度。提出了一种基于获得的数据并确定通过地面平均值测量温度的确切高度的校准地面仪器（Fabry-Perot干涉仪）的方法。基于温度以线性方式连接的假设，温度连接的系数由最小二乘法确定。我们使用有关Saber TimeD和MLS Aura卫星仪器以及位于SB RAS ISTP的Fabry-Perot干涉仪获得的2017 - 2018年上层大气温度的信息，观察557.7 NM Oxygen Line line SB RAS ISTP，发射高度为557.7 nm oxygen Line。使用干涉仪在92 km的高度上获得了约0.99的比例因子，并获得了约120K的位移系数，该干涉仪为92 km的高度获得了干涉仪温度的季节性变化，这与Saber Timed获得的季节性变化最紧密地对应。然后，系数可以用作干涉仪的校准值。
An approach is demonstrated for comparing the temperature of the upper atmosphere obtained by ground-based and satellite methods. A method for calibrating ground-based instruments (Fabry-Perot interferometer) based on the data obtained and determining the exact altitude at which the temperature was measured by ground-based means is proposed. Based on the assumption that the temperatures are connected in a linear fashion, the coefficients of the temperatures connection are determined by the least squares method. We use information on the temperature of the upper atmosphere for 2017-2018 obtained by the SABER TIMED and MLS Aura satellite instruments, and by the Fabry-Perot interferometer located at the Tory geophysical observatory of the ISTP of the SB RAS observing the 557.7 nm oxygen line, the emission height is ~ 100 km. The scale factor about 0.99 and the displacement coefficient about 120K were obtained for the temperature data using an interferometer at a height of 92 km for which the seasonal variation of the temperatures of the interferometer most closely corresponds to the seasonal variation of the temperatures obtained by SABER TIMED. The coefficients can then be used as calibration values for the interferometer.
