Abstract
Regional approaches to estimate the carbon budget of Italian forest
ecosystems using Process-Based Models (PBMs), have been applied by several
national institutions and researchers. Gross and net primary productivity (GPP and
NPP) have been estimated through the PBMs simulations of carbon, water, and
elemental cycles driven by remotely sensed data set and ancillary data. In particu-
lar the results of the GPP and NPP estimations provided by the implementation
of two hybrid models are presented. The first modeling approach, based on the
integration of two widely used models (C-fix and BIOME-BGC), has been applied
to simulate monthly GPP and NPP values of all Italian forests for the decade
