Abstract
The biogeochemical model BIOME-BGC is capable to estimate the main ecophysiological
processes characterising all terrestrial ecosystems. To this aim it
needs to be properly adapted to reproduce the behaviour of each biome type
through a calibration phase. The aim of this paper is to adapt BIOME-BGC to reproduce
the evapotranspiration (ET) and photosynthesis (GPP) of Mediterranean
macchia spread all over Italy. Ten different sites were selected in the
Centre-South of Italy and their gross primary production (GPP) was estimated
by applying a parametric model, C-Fix, based on remotely sensed data for ten
years (1999-2008). These monthly data were then used to calibrate BIOME-BGC
through an iterative process which led to reproduce the spatial and temporal
GPP variations found by C-Fix. The calibrated model was then applied to simulate
the ET and GPP of two Italian sites characterised by the presence of an
eddy flux tower; its performances were evaluated against ground data by common
statistics. The results obtained indicate that, after a proper calibration
phase, BIOME-BGC can be applied to estimate the evapotranspiration and photosynthesis
of Mediterranean macchia with a good accuracy, strictly dependent
on the input data utilised.
