Abstract:

On the basis of the analysis of atmospheric carbon dioxide concentration variations and the annual mean air temperature at Syowa Station, Antarctica in 1984-1988 period, the following results are easily obtained. (1) The annual mean values of the atmospheric carbon dioxide concentration are gradually increased and equal to 342.59, 343,80, 345.15, 346,83 and 348.82 ppmv for 1984, 1985, 1986, 1987 and 1988, respectively. Its growrh rates of the year to year are 1.21,1.35, 1.68 and 1.99 ppmv/yr, for 1984-1985, 1985-1986, 1986-1987 and 1987-1988, respectively and are raised year after year. The seasonal variations are observed and the maximum concentration in spring and the minimum concentration in autumn. (2) The increased tendency of the annual mean value of the atmospheric carbon dioxide concentration is consistent with that of the annual mean value of air temperature*
