PDG-Arena: an ecophysiological model for characterizing tree-tree interactions in heterogeneous and mixed stands

Table 3 Matrix of similarity between simulated GPP from CASTANEA and PDG-Arena

	CASTANEA	PDG-Arena	PDG-Arena	PDG-Arena
	(RM)	(RM)	(R)	(O)
CASTANEA (RM)	100.0	-	-	-
PDG-Arena (RM)	99.8	100.0	-	-
PDG-Arena (R)	99.3	99.5	100.0	-
PDG-Arena (O)	97.7	98.5	99.0	100.0

Different types of inventories are considered: “RM” (regularized and monospecific, i.e., without species interactions), “R” (regularized, but with species interactions), and “O” (original inventories). Similarity is expressed using the correlation coefficient (in %) of the simulated gross primary production for the 39 stands over the 1996–2013 period
