Table 1.
Selected PREBAS outputs used in this study. The interlinked submodels of PREBAS simulate process-based forest growth (CROBAS), daily canopy gas exchange (PRELES) and soil carbon through annual litter inputs (YASSO). For references and further details of the submodels, see the main text

| Dec. vol | Deciduous stem volume | m3 ha−1 | CROBAS |
| Age | Dominant tree age | years | CROBAS |
| Species | Dominant tree species | Pine, spruce, deciduous | CROBAS |
