我们已经开发了一个复杂的拉曼激光雷达数值模型来模拟两个地基拉曼水汽激光雷达系统的性能。在使用这些地面测量数据验证模型后，我们使用该模型模拟了机载拉曼激光雷达在白天和夜间条件下对各种水汽条件的水汽测量能力。结果表明，在许多情况下，白天的测量具有可比的质量，现有的机载差分吸收水汽激光雷达，而夜间的测量提高了空间和时间分辨率。此外，机载拉曼激光雷达可以提供差分吸收激光雷达技术难以或不可能的测量。
We have developed a sophisticated Raman lidar numerical model to simulate the performance of two ground-based Raman water-vapor lidar systems. After verifying the model using these ground-based measurements, we then used the model to simulate the water-vapor measurement capability of an airborne Raman lidar under both daytime and nighttime conditions for a wide range of water-vapor conditions. The results indicate that, under many circumstances, the daytime measurements possess comparable quality to an existing airborne differential absorption water-vapor lidar whereas the nighttime measurements have improved spatial and temporal resolution. In addition, an airborne Raman lidar can offer measurements that are difficult or impossible with the differential absorption lidar technique.
