We verified the feasibility of an alternative solution to generate temperature and pressure profiles with the U.S. standard atmosphere model (USSA-76). We simultaneously integrated this model with conventional meteorological parameters measured by a weather station in the course of estimating the refractive index structure constant ( 2). Moreover, a continuous-time-series estimation method of the refractive index structure constant was established within the marine atmospheric boundary layer (ABL) based on wind data obtained from a coherent Doppler wind lidar (CDWL). We also analyzed the optical turbulence characteristics induced by wind shear during the conducted experiment. Laminated and patchy stratified turbulences, which affect the performance of imaging and light transmission systems, were found within the marine ABL. Additionally, the relationship between the ABL and all atmospheric optical turbulence factors shows that the ratio of marine ABL in the entire layer differs from that reported in previous studies. Moreover, the influence of thermal turbulence factors within the marine ABL was less than that of the entire layer in our case. We report a real-time 2 estimation method based on a CDWL. The characteristics of the marine ABL 2 constitute a reference for optoelectronic applications.
我们验证了使用美国标准大气模型（USSA - 76）生成温度和压力剖面的替代解决方案的可行性。在估算折射率结构常数（ 2）的过程中，我们将该模型与气象站测量的传统气象参数同时进行整合。此外，基于从相干多普勒风激光雷达（CDWL）获得的风数据，在海洋大气边界层（ABL）内建立了折射率结构常数的连续时间序列估计方法。我们还分析了实验过程中风切变引起的光学湍流特性。在海洋ABL内发现了影响成像和光传输系统性能的层状和片状分层湍流。此外，ABL与所有大气光学湍流因子之间的关系表明，海洋ABL在整个层中的比例与先前研究报道的不同。而且，在我们的案例中，海洋ABL内热湍流因子的影响小于整个层的影响。我们报告了一种基于CDWL的实时 2估计方法。海洋ABL 2的特性为光电应用提供了参考。
