Description

Looking at some PFTs in Europe, it's not clear that the allometric relationships are correct. These were originally derived from forest inventory results. However, the parameters for PFT7, for example, suggest that trees will only be 25 meters tall if they have a diameter of one meter. Trees in the boreal zone will never have a diameter of one meter, but it's not uncommon to see trees that are 18-20 meters tall. Therefore, perhaps the tree height in the model is too small. This could be checked, as it would likely have an impact on the coupling.

PFT6 was also flagged for checking.
