- 摘要:
- 激光测风雷达是近年来常用的大气探测设备,具有良好的性能,在风场反演方面的应用表现较为出色。然而,大气中有干扰激光探测的成分,激光测风雷达也不可避免地会产生相应的噪声。为减小这些干扰带来的数据误差,选取一种可以对激光测风雷达径向风速进行质量控制的方法。研究结果表明:通过对激光测风雷达径向风速的逐级质控,在多种干扰因素影响下的径向风速数据的质量会大大增强可信度; 质控后的径向风速也更适合实现风场反演算法,在数据质量的层次上为二次产品的开发打下良好的基础。
- Abstract:
- In recent years, wind lidar is commonly used atmospheric detection equipment. Because of its good performance, it performs well in the application of wind field inversion. However, there are components in the atmosphere that interfere with laser detection, and the wind lidar itself will inevitably generate corresponding noise. In order to improve the data errors caused by these disturbances, a method for quality control of the radial wind speed of lidar wind measurement was selected. Generally, the research results show that: through the quality control of the radial wind speed of the wind lidar step by step, the data quality of the radial wind speed under the influence of various interference factors will greatly enhance the credibility; the radial wind speed after quality control is also improved. It is suitable for the realization of further wind field retrieval algorithm, which lays a good foundation for the development of secondary products at the level of data quality.
