介绍了中国科学院安徽光学精密机械研究所研制的测量对流层大气二氧化碳的ARL-1 Raman激光雷达系统,以Nd:YAG三倍频作为发射光源,接收大气中氮气和二氧化碳的Raman后向散射信号,反演大气中的二氧化碳混合比分布。在ARL-1 Raman激光雷达系统中,设计了测量Rama激光雷达常数的标定装置,实验结果表明,定标光源LED的稳定度可达99.5%。利用该系统对边界层二氧化碳进行了初步定量测量和分析。
The ARL-1 Raman laser radar system for measuring atmospheric carbon dioxide in the troposphere, which is developed by Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences, is introduced. Raman backscattering signals of nitrogen and carbon dioxide in the atmosphere are received by using Nd: YAG triplet as a light source. Play the atmosphere of carbon dioxide mixture ratio distribution. In the ARL-1 Raman laser radar system, a calibration device for measuring the Rama Lidar constant is designed. The experimental results show that the stability of the calibrated LED can reach 99.5%. The system was used to conduct a preliminary quantitative measurement and analysis of carbon dioxide in the boundary layer.
