Abstract;Numerical experiments using atmospheric transport model were implemented with regional and monthly pulse CO2 fluxes to evaluate their contributions to CO2 concentrations at observation stations. Using evaluated contributions and observed CO2 concentrations, seasonal variation of carbon flux from biosphere was investigated. The results showed that high amplitudes of observed seasonal CO2 variations at northern high latitudes are produced by large absorption at northern North America and around Siberia during summer. It is also suggested that these two strong absorptions in summer may be the most significant discrepancies between seasonal CO2 flux variation of real biosphere and that of the biosphere model used in our prior study.
