摘要:

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Raman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。

Abstract:

ARL-1 Raman lidar system developed in Anhui Institute of Optics and Fine Mechanics was introduced for atmospheric CO2 measurements. It is based on third harmonic of Nd:YAG laser. This system emits laser beam at wavelength of 354.7 nm into atmosphere and collects Raman backscattering lights from atmospheric N2 and CO2 stimulated by laser beam. Mixing ratio profile of CO2 can be calculated with Raman backscattering signals of N2 and CO2. In ARL-1 Raman lidar system, a setup for lidar constant calibration was designed. The experimental result shows that the stability of LED light intensity can reach up to 99.5%. Atmospheric CO2 measurements in PBL were carried out with the Raman lidar system.

Key words: atmospheric optics, Raman lidar, CO2, N2, lidar constant calibration
