The M-SDGVM was evaluated against the eddy-covariance measurements of seasonal and annual carbon and water fluxes at 15 forest sites within the EUROFLUX project from 1996 to 1998. Generally, the M-SDGVM can reasonably reproduce the seasonal trend of carbon and water exchange among different sites. It correctly simulated the net uptake of carbon during spring and summer months and the release of carbon during autumn and winter months. And the M-SDGVM also did a better job in predicting the release of water to the atmosphere during all the seasons. The results shown here suggest that in general the M-SDGVM can be used as a useful tool for studies of climate change impacts on carbon and water cycles of forests in Europe and their possible feedbacks. However, the model shows some biases at part of the sites. Analyzing and quantifying the case studies with poor performance will lead to further insights on modifications and improvements of the current version of M-SDGVM.
