where
SCA
is the Stem C Allocation ratio,
BEF
the volume of above ground bio-
mass/standing volume Biomass Expansion Factor (both dimensionless), and
BWD
is the Basic Wood Density (Mg m
−
3
). The
SCAs
of the six forest types are those of
BIOME-BGC, while
BEFs
and
BWDs
are taken again from Federici et al. (
2008
).
The multiplication by 2 accounts for the transformation from carbon to dry matter,
and that by 100 for the change in magnitude from g m
−
2
to Mg ha
−
1
.
The CAI modeled values were finally validated through comparison with the
CAI measurements taken during the INFC, considering only the Regions where
the presence of each forest type was significant (at least 10 1-km
2
pixels). The
