  - Projections of the future carbon and water cycles rely on knowledge on how forests
    will respond to rising atmospheric CO2. Experiments with elevated CO2 are logistically
    challenging and carbon pools and fluxes are difficult to measure and upscale due
    to their spatiotemporal heterogeneity. Therefore, it is important to combine the
    knowledge derived from experimental results with modeling. Here, we systematically
    compare data from a free air CO2 enrichment (FACE) experiment in a mature deciduous
    forest in Switzerland with realizations from an ecohydrological model (Tethys–Chloris).
    We test whether a mechanistic ecohydrological model is able to simulate physiological
    plant responses under ambient and elevated CO2 concentration. We overcome measurement
    limitations by quantifying differences in response to ambient and elevated CO2
    over ten years. The reliability of model realizations is demonstrated by comparing
    simulations with field observations of stomatal conductance, sap flow, leaf and
    fruit litter, and stem growth. The model successfully captures the observed CO2-induced
    difference in stomatal conductance and transpiration and its sensitivity to atmospheric
    demand, as well as qualitative changes in soil moisture. The simulated differences
    between CO2 scenarios generally fall within the uncertainty of experimental observations,
    both for the carbon and water balance. Simulated total evapotranspiration is 2.8%
    (18 mm yr−1) lower and soil moisture 1.2% higher in the CO2-enriched scenario.
    Latent and sensible heat are modified by ca. 1 W m−2. Net primary production is
    simulated to increase by 19.8% and allocation to stem growth is 53 gC yr−1 m−2
    higher in the elevated CO2 scenario, which represents the limit of the detection
    threshold of the experiment. Results show that while ecohydrological models can
    be used to reliably simulate multi-year energy, water, and carbon fluxes at the
    stand level, testing carbon allocation remains critical with current accuracy
    of field measurements. Uncertainties due to the simplified carbon allocation scheme
    are shown to be more significant for carbon than for energy and water fluxes.
    Generally, we conclude that for this type of forest, differences in annual energy
    and water fluxes induced by elevated CO2 are likely to be less than 10%.@eng
