摘要: 利用大口径闪烁仪和QHTP-2型温度脉动仪对新疆戈壁地区近地面大气折射率结构常数进行对比观测。结果表明:两种仪器测量所得大气折射率结构常数具有较好的相关性,皮尔森相关系数达0.68。大口径闪烁仪所测结果符合新疆戈壁地区近地面大气湍流强度日变化特征,与温度脉动仪测量结果随时间变化趋势基本一致。两种仪器测量结果在数量级上存在的差异,可能是由测量原理、测量高度、大气稳定状态等因素造成的。

Abstract: The atmospheric refractive index structure constant near ground in gobi region was measured by using the large aperture scintillometer and the micro-thermal meter at the same time. The results show that there was a good correlation between the values of atmospheric refractive index structure constant by two kinds of instruments with the Pearson correlation coefficient up to 0.68. The measuring result by the large aperture scintillometer can show the diurnal variation character near ground in gobi region, and it was consistent with that by the micro-thermal meter. However, the measured values by the large aperture scintillometer were almost bigger in magnitude than by the micro-thermal meter because of different measurement factors.

Key words: atmospheric optics, atmospheric refractive index structure constant, large aperture scintillometer(LAS), micro-thermal meter
