Monte Carlo simulations are used to study the signals generated by the scatter from aerosol in the marine boundary layer and reflection off a rough sea surface when a laser pulse at 1.06microm passes down through the atmosphere. The model estimates the probability of photons being returned to a receiver collocated with the laser which has two detectors: one with a narrow field of view (lidar detector) and another with a wide field of view where the directly reflected photons are blocked (aureole detector). The simulations are done for nine different aerosol size distributions, three different boundary layer depths, and three different wave conditions. A comparison of the boundary layer optical depth and normalized aureole signal is presented. In addition, a comparison is made between the normalized aureole signal at 1.06 microm (when the detector field of view is reduced) and boundary layer optical depths at 3.75 microm.
当波长为1.06微米的激光脉冲穿过大气层时，蒙特卡罗模拟被用于研究海洋边界层中气溶胶散射以及粗糙海面反射所产生的信号。该模型估计光子返回与激光器并置的接收器的概率，该接收器有两个探测器：一个具有窄视场（激光雷达探测器），另一个具有宽视场，其中直接反射的光子被阻挡（光环探测器）。针对九种不同的气溶胶粒径分布、三种不同的边界层深度和三种不同的海浪条件进行了模拟。给出了边界层光学厚度与归一化光环信号的比较。此外，还对1.06微米处的归一化光环信号（当探测器视场减小时）与3.75微米处的边界层光学厚度进行了比较。
