1983年在南极洲的Syowa站开始了对大气二氧化碳浓度的精确测量。对迄今为止获得的数据的初步检查表明：(1)没有观察到规律的日变化；(2)有时观测到不规则变化，幅度极小，最大0.2 PPMV；(3)季节变化，4月中旬浓度最低，10月中旬浓度最高；检测到的峰间振幅约为1.2 PPMV；(4) 1983年和1984年的年平均CO2浓度分别为341.2和342.6 ppmv。
Precise measurements of the atmospheric CO2 concentration were initiated at Syowa Station, Antarctica in 1983. Preliminary inspection of the data obtained up to the present showed that: (1) a regular diurnal variation is not observable; (2) irregular variations are sometimes observed with extremely small amplitudes of 0.2 ppmv at most; (3) a seasonal variation with the minimum concentration in mid-April and the maximum concentration in mid-October; and peak-to-peak amplitudes of about 1.2 ppmv are detected; (4) annual mean values of the CO2 concentration are 341.2 and 342.6 ppmv for 1983 and 1984, respectively.
