• Main responsibles: Nicolas Vuichard
• Objectives / roadmap:
  • FIRST objective) prepare a version of the coupling between C and N cycles that works globally and in a coupled mode with LMDz, based on the "merged OCN-ORC-CAN version" of Nicolas.
  • SECOND objective (in Parallele ?): preparation for the use of SPITFIRE and possibly GM ? In the case of SPITFIRE, try at the same time to prepare for the coupling with ORC-CAN.
  • THIRD objective: integration of the Carbon permafrost from the ORCHIDEE-MICT branch
  • other objectives to be defined later?

• Status of the ORCHIDEE-MICT branch

presentation FM​

• Latest C permafrost developments

presentation DZ​
These developments need to be first integrated into the ORCHIDEE-MICT branch from DZ's personal branch.
It is agreed that this C permafrost version should be the one integrated into the TRUNK within the first semester of 2016. If u is set to 0, this is equivalent to the former C permafrost version.
PP says that some help could be given on this subject through the CRESCENDO project.

• MICT Forcesoil

presentation CY/YH​
CY and YH are doing sensitivity tests and will propose a forcesoil protocol in a few weeks.
DZ has reported on a bug when forcesoil is forced with a monthly time-step. When the bug is fixed, we hope to go from the daily time-step, which gives correct results but is time-consuming, back to the monthly time-step.
PC is working on an updated analytical spinup, as there are now second-order differential equations.
