This study evaluates the performances of the new version (v.5.1) of 3D-CMCC
Forest Ecosystem Model (FEM) in simulating gross primary productivity (GPP),
against eddy covariance GPP data for 10 FLUXNET forest sites across Europe.
A new carbon allocation module, coupled with new both phenological and
autotrophic respiration schemes, was implemented in this new daily version.
Model ability in reproducing timing and magnitude of daily and monthly GPP
fluctuations is validated at intra-annual and inter-annual scale, including
extreme anomalous seasons. With the purpose to test the 3D-CMCC FEM
applicability over Europe without a site-related calibration, the model has
been deliberately parametrized with a single set of species-specific
parametrizations for each forest ecosystem. The model consistently
reproduces both in timing and in magnitude daily and monthly GPP variability
across all sites, with the exception of the two Mediterranean sites. We find
that 3D-CMCC FEM tends to better simulate the timing of inter-annual
anomalies than their magnitude within measurements' uncertainty. In six of
eight sites where data are available, the model well reproduces the 2003
summer drought event. Finally, for three sites we evaluate whether a more
accurate representation of forest structural characteristics (i.e. cohorts,
forest layers) and species composition can improve model results. In two of
the three sites results reveal that model slightly increases its
performances although, statistically speaking, not in a relevant way. |
