  - Dynamic vegetation models have been widely used for analyzing ecosystem dynamics
    and their interactions with climate. Their performance has been tested extensively
    against observations and by model intercomparison studies. In the present analysis,
    Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS), a state-of-the-art
    ecosystem model, was evaluated by performing a global sensitivity analysis. The
    study aims at examining potential model limitations, particularly with regard
    to long-term applications. A detailed sensitivity analysis based on variance decomposition
    is presented to investigate structural model assumptions and to highlight processes
    and parameters that cause the highest variability in the output. First- and total-order
    sensitivity indices were calculated for selected parameters using Sobol's methodology.
    In order to elucidate the role of climate on model sensitivity, different climate
    forcings were used based on observations from Switzerland. The results clearly
    indicate a very high sensitivity of LPJ-GUESS to photosynthetic parameters. Intrinsic
    quantum efficiency alone is able to explain about 60% of the variability in vegetation
    carbon fluxes and pools for a wide range of climate forcings. Processes related
    to light harvesting were also found to be important together with parameters affecting
    forest structure (growth, establishment, and mortality). The model shows minor
    sensitivity to hydrological and soil texture parameters, questioning its skills
    in representing spatial vegetation heterogeneity at regional or watershed scales.
    In the light of these results, we discuss the deficiencies of LPJ-GUESS and possibly
    that of other, structurally similar, dynamic vegetation models and we highlight
    potential directions for further model improvements.@eng
