摘要回顾了利用激光雷达数据进行气象学和空气质量应用的边界层混合高度的概念，并提出了根据各种类型的低对流层相干多普勒激光雷达测量值估计混合高度的新算法。从多普勒激光雷达数据得到的速度方差分布展示了对混合高度估计的直接应用，而其他类型的激光雷达分布展示了与方差分布的关系，因此也可用于混合高度估计。该算法被应用于船基，高分辨率多普勒激光雷达（HRDL）的速度和后向散射信号的测量R/V罗纳德H。布朗在得克萨斯州空气质量研究（TexAQS）2006年，以证明该方法，并产生混合高度估计该实验。多普勒激光雷达导出的速度测量的这些组合以前没有被应用到分析的边界层混合高度在水或其他地方。一个比较的…
Abstract The concept of boundary layer mixing height for meteorology and air quality applications using lidar data is reviewed, and new algorithms for estimation of mixing heights from various types of lower-tropospheric coherent Doppler lidar measurements are presented. Velocity variance profiles derived from Doppler lidar data demonstrate direct application to mixing height estimation, while other types of lidar profiles demonstrate relationships to the variance profiles and thus may also be used in the mixing height estimate. The algorithms are applied to ship-based, high-resolution Doppler lidar (HRDL) velocity and backscattered-signal measurements acquired on the R/V Ronald H. Brown during Texas Air Quality Study (TexAQS) 2006 to demonstrate the method and to produce mixing height estimates for that experiment. These combinations of Doppler lidar–derived velocity measurements have not previously been applied to analysis of boundary layer mixing height—over the water or elsewhere. A comparison of the ...
