abstract = {Vegetation plays an important role in global carbon and
water cycles. Long-term environmental changes modify
vegetation distributions and consequently impact fluxes of
carbon, water and energy. Vegetation dynamic models are
useful tools to analyze terrestrial ecosystem processes and
can simulate the impact of vegetation structure changes on
carbon and water cycles and their interactions with climate
when coupled to land surface models. Because of the
complexity to represent plant growth processes, these models
typically have a large number of parameters that can
potentially contribute to uncertainty in model results and
need to be adequately parameterized. In this study, we used
the Community Land Model (CLM v5) coupled to the
Functionally Assembled Terrestrial Simulator (FATES) and
applied it to four forest sites from the database of
European Long-Term Ecosystem Research Infrastructures
(eLTER) which provides a wide range of observational data to
calibrate and evaluate vegetation models. Using this
database, we performed sensitivity analysis to evaluate
parameter uncertainties in model results for forest growth,
gross primary production, leaf area index,
evapotranspiration, soil water content and soil temperature.
We also explored the sensitivity of model parameters for
different vegetation distributions and climate conditions.
The results of this study allow us to understand the
vegetation dynamics and their impact on carbon and water
fluxes which will be helpful to improve model
parameterization and to provide more accurate estimates of
carbon and water fluxes and climate model projections.},
