Abstract: To strengthen scientific management and sharing of greenhouse gas data obtained from atmospheric background stations in China,it is important to ensure the standardization of quality assurance and quality control method for background CO2 sampling and analysis. Based on the greenhouse gas sampling and observation experience of CMA,using portable sampling observation and WSCRDS analysis technique as an example,the quality assurance measures for atmospheric CO2 sampling and observation in the Waliguan station（ Qinghai）,the glass bottle quality assurance measures and the systematic quality control method during sample analysis,the correction method during data processing,as well as the data grading quality markers and data fitting interpolation method were systematically introduced. Finally,using this research method,the CO2 sampling and observation data at the atmospheric background stations in 3 typical regions were processed and the concentration variation characteristics were analyzed,indicating that this research method could well catch the influences of the regional and local environmental factors on the observation results,and reflect the characteristics of natural and human activities in an objective and accurate way.
