我们描述了一种组合式拉曼激光雷达的性能。采用旋转拉曼技术和积分技术同时测量温度。此外，还测量了粒子消光系数和后向散射系数以及水蒸气混合比。在系统的前一阶段，仪器问题限制了性能。我们描述了我们如何重建仪器并克服了这些限制。结果表明，在相同的空间分辨率和精度下，旋转拉曼温度测量的测量时间减少了约4.3倍，并且其范围首次可以扩展到平流层上层。
We describe the performance of a combined Raman lidar. The temperature is measured with the rotational Raman technique and with the integration technique simultaneously. Additionally measured parameters are particle extinction and backscatter coefficients and water vapor mixing ratio. In a previous stage of the system, instrumental problems restricted the performance. We describe how we rebuilt the instrument and overcame these restrictions. As a result, the measurement time for the same spatial resolution and accuracy of the rotational Raman temperature measurements is reduced by a factor of approximately 4.3, and their range could be extended for the first time to the upper stratosphere.
