Eddy covariance measurements have been conducted to monitor seasonal and annual variability in CO2 exchanges between the atmosphere and the cool-temperate deciduous forest ecosystems in Northern Japan since 2003. An analysis on dynamic changes in the forest has been made based on forest inventory data over a decade since 1998. In recent years, an atmosphere-forest dynamics model has been developed and was applied to the forest to examine whether or not the model describes realistically forest dynamics and the atmosphere-forest CO2 exchange. In this paper, we reported the observed and simulated results on forest dynamics and the atmosphere-forest CO2 exchange. From the report, we specified the importance of the effect of structural and physiological changes in a forest stand on the atmosphere-forest CO2 exchange and, therefore, an additional improvement of the developed atmosphere-forest dynamics model through eco-physiological approaches to elucidate atmosphere-biosphere interaction in the future.
