      abstract     = {Land surface models (LSMs), when coupled with vegetation
                      dynamic models, serve as useful tools to understand how
                      ecosystem changes impact carbon and water cycling and
                      interact with the climate. However, simplified vegetation
                      parameterization schemes within LSMs makes it challenging to
                      capture the full dynamics of vegetation processes, leading
                      to significant uncertainties in the simulated ecosystem
                      variables. To assess these uncertainties stemming from
                      different model complexities in vegetation representations,
                      we conducted model simulations employing different
                      vegetation parameterization schemes: (1) using static
                      vegetation distribution and prescribed leaf area index
                      (LAI), (2) simulating full carbon cycle with static
                      vegetation, and (3) explicitly simulating fully dynamic
                      carbon and vegetation distribution.Here, we use a vegetation
                      demographic model, the Functionally Assembled Terrestrial
                      Simulator (FATES) coupled with the Community Land Model
                      (CLM5) to evaluate the representation of vegetation dynamics
                      and related surface fluxes across multiple forested sites in
                      Europe selected from the Integrated Carbon Observation
                      System (ICOS) station network. Comparison with observations
                      showed that the CLM5-FATES model, with the full vegetation
                      dynamics implementation, exhibited better model performance
                      in simulating gross primary production (GPP) than the runs
                      with prescribed leaf-area climatology. However, the model
                      showed an underestimation of LAI with low interannual
                      variations compared to satellite-based MODIS data,
                      particularly for sites with evergreen forests. Additionally,
                      the model's performance in simulating hydrological fluxes
                      (such as soil moisture (SM) and evapotranspiration (ET))
                      remained consistent across all sites, irrespective of model
                      complexity. Future work will explore uncertainties in
                      simulated vegetation structure and distributions and
                      parameter optimization to improve model performance in
                      simulating forest growth and composition.},
