Description

In ORCHIDEE-CN-CAN we no longer want to consider the gaps in between the vegetation as bare soil. What happens in a PFT stays in the PFT! It is not clear whether it is realistic to remove tot_bare_soil when using the single layer energy budget. It should work with the multi-layer energy budget. Seems that in ORCHIDEE-DOFOCO part of the calculations with and for tot_bare_soil where removed but several calculations were left

Also check the use of frac_bare. Do we need this? It is being calculated in slowproc. As is tot_bare_soil.

  • Resolution set to fixed
  • Status changed from new to closed

Across r5656, r5657 and r5659 the flag ok_bare_soil_new was added to slowproc.f90 and was tested. This flag allows switching between two approaches to calculate tot_bare_soil. If set the false, the old view is represented in the calculations, hence, gaps within the canopy are moved into the bare soil variable. If set to true the calculations represent a more ecological view in which the gaps are just part of the ecosystem.
