Since 1993,CO_2 concentration and its flux between the atmosphere and a temperate forest ecosystem have been examined in the central part of Japan (the Takayama site). Daily variation of CO_2 concentration at the Takayama site during three days in July was compared with the results of a numerical simulation with 2.5km grid width, in which both the CO_2 flux of anthropogenic origin and that from the ecosystem were considered. The CO_2 flux from the ecosystem was estimated from the data at the Takayama site and extended to all the central part of Japan with the aid of a vegetation map. The anthropogenic contamination of CO_2 was also investigated. The maximum CO_2 concentration appeared at midnight due to the onset of downslope wind with lower CO_2 concentration.
