中文摘要	差分吸收激光雷达是高精度测量大范围二氧化碳浓度的有效手段。研究了机载路径积分差分吸收激光雷达测量二氧化碳柱线浓度的主要误差项,分析了这些误差项导致的二氧化碳柱线浓度反演误差。介绍了机载差分吸收激光雷达基本工作原理,并理论分析了大气温度、压强和水汽不确定性误差,激光频率稳定性和飞机姿态速度测量不确定性等系统误差,以及不同地表反射率产生的随机误差。分析结果表明:在二氧化碳浓度380 ppm(1 ppm=10~(-6))时,机载激光雷达二氧化碳柱线浓度综合测量误差约为0.71 ppm,满足1 ppm的二氧化碳柱
英文摘要	Differential absorption lidar is an effective methods for high -precision CO_2 concentration measurements. In this paper, the major error sources of airborne differential absorption lidar CO_2 measurement were studied, and CO_2 concentration errors caused by them were analyzed. The airborne differential absorption lidar principle was introduced first, CO_2 concentration errors from atmospheric temperature, pressure and water vapor uncertainties, laser frequency stability and the aircraft speed and attitude measurements uncertainties, as well as random error were analyzed. The results show that airborne differential absorption lidar measured CO_2 column concentration error is about 0.71 ppm (1 ppm=10~(-6)) for 380 ppm atmosphere CO_2 concentration, which meets the 1 ppm accuracy requirement of CO_2 concentration measurement.
