Abstract

Supplementary information 1. Description of ORCHIDEE in function of the aggregation model 1.1. Dependency of tree growth on climate For deciduous trees, when the phenological thresholds are exceeded in ORCHIDEE r5698, leaves emerge using carbon from the reserve pool and as such an essential condition for carbon assimilation is fulfilled. Carbon assimilation is calculated following the analytical solution of the Farquhar and Ball and berry model, defined by Yin and Struik (Yin and Struik, 2009):
