论文摘要
对光学空间光学器件（FSO）和基于地面的光学天文学的感兴趣的光学折射率结构参数$ c_n^2 $的知识，因为它描述了接收到的光波的预期闪烁的强度。这里使用来自辐射测量的气象量作为估计大气中$ C_N^2 $概况的输入，将重点放在模型上。提出了依赖$ C_N^2 $统计定义的模型，并应用于Trappes（France）和HI（美国）HILO（美国）的近期高密度辐射配置文件。它也与来自T-Rex广告系列的热度测量值进行了比较。该模型使得仅使用压力和温度测量值鉴定孤立的湍流层，从而为光学位点选择铺平了道路。与受文献启发的基于Tatarskii的模型相比，它提供了类似的性能。
Knowledge of the optical refractive index structure parameter $C_n^2$ is of interest for Free Space Optics (FSO) and ground-based optical astronomy, as it depicts the strength of the expected scintillation on the received optical waves. Focus is given here to models using meteorological quantities coming from radiosonde measurements as inputs to estimate the $C_n^2$ profile in the atmosphere. A model relying on the $C_n^2$ statistical definition is presented and applied to recent high-density radiosonde profiles at Trappes (France) and Hilo, HI (USA). It is also compared to thermosonde measurements coming from the T-REX campaign. This model enables to obtain site-specific average profiles and to identify isolated turbulent layers using only pressure and temperature measurements, paving the way for optical site selection. It offers similar performance when compared to a Tatarskii-based model inspired by the literature.
