[Abstract]

The net ecosystem production (NEP) at Takayama forest was parameterized with temperature, available photosynthetic active radiation (APAR), and leaf area index (LAI). The variation of NEP due to temperature rise and change of APAR was estimated throughout a year. The distribution of CO₂ concentration and its time variation over central part of Japan was calculated for three days to check the parameterization based on Takayama data. The variation of NEP due to change of cloud amount in the area was also estimated.
