中国科学院安徽光学精密机械研究所研制了一台ARL-1二氧化碳拉曼激光雷达,结合实际大气条件, 利用拉曼激光雷达的观测例子和分析仪观测结果,分析了拉曼激光雷达测量大气二氧化碳的不确定性。 分析结果表明,拉曼激光雷达在对流层低层具有良好的稳定性和较高的测量精度,在较好的天气条件下, 1 km高度范围内,ARL-1拉曼激光雷达的测量不确定性可控制在1.2 ppm内,在2 km高度范围内可控制在2.5 ppm内。

A Raman lidar was developed for atmospheric CO2 measurements in the low troposphere in Anhui Institute of Optics and Fine Mechanics, Chinese Academy of Sciences. Combined with real atmospheric condition, atmospheric CO2 uncertainty was analyzed using the Raman lidar measurement cases and observation results by CO2 analyzer. Analyzed results show that the lidar reveals fine stability and higher accuracy. For example, it’s uncertainty can be limited within 1.2 ppm up to 1km altitude and 2.5 ppm up to 2 km altitude under good weather condition.
