摘要
按 WMO 关于开展全球 CO_2监测的要求,在对引进设备进行改进的情况下,建立了我国开展大气 CO_2本底浓度连续测量的红外气体分析测量系统及有关方法.系统的测量精度优于0.1ppm,完全满足全球本底测量的要求,并具有较好的国际可比性.在此基础上,首次取得了我国大陆上空大气 CO_2的本底浓度资料.
The technique for high precision measurement of atmospheric CO_2 has been deve-loped by improving of the import nondispersive infrared CO_2 analyzer.The system preci-sion with better than 0.1ppm is attained and possessed the better comparability.Itmeets the requirements of the Global Atmosphere Watch of WMO.On the basis of mea-surements in situ,the data of background CO_2 concentrations over the continent of Chinaare first obtained.
