Problem in Woody biomass

Description (last modified by nvuilsce)

Woody biomass is ~2 times too high, compare to the version 2.0 and to acceptable values from literature.

Based on the monitoring diagnostics, the gpp and the allocated npp to wood are not so different between versions (although they are higher with the current trunk version with the nitrogen).

The flow of carbon from wood to litter is also similar from one version to another. This seems to indicate a problem in the residence time of the woody pool (a priori it should be the same value than in the version 2.0) but maybe not...



This needs a deeper analysis. This global behavior may hide specific regional patterns or differences for only few PFTs.

Said today: on going work. This needs only to be done in ORCHIDEE_3, no need to report into CN-CAN.
