摘要:

中科院安徽光机所研制了一台ARL-1二氧化碳拉曼激光雷达,本文结合实际大气条件,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,1km高度范围内,ARL-1拉曼激光雷达的测量不确定性可控制在1.2ppm内,在2km高度范围内可控制在2.5ppm内。

Abstract:

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 were analyzed using the Raman lidar measurement cases and observation results by CO2 analyzer. Analyzed results show that our lidar reveals fine stability and higher accuracy.For example, it is uncertainty can be limited within 1.2ppm up to 1km altitude and 2.5ppm up to 2km altitude under good weather condition.

Key words: Raman lidar, atmospheric CO2, uncertainty
