MICT-IMBALANCE-P Development Lines

Short Term

=> Would be good to have this as part of MICTV7 if we want to give to the Trunk the permafrost carbon.

  • Gross land use change processes & harvest (Chao)

This is a major new development. We have to check implications for memory and CPU and should have Gross-LCC and Net-LCC as two options activable => To be decided by Chao.

  • Deforestation fires (Chao)

It seems to have minor implications on the rest of the model and could be added in MICTV7 => To be decided by Chao.

  • New driver (from the TRUNK)

=> It seems to be important in the near future (and could help everyone). I would like to see CPU tests with / without the new driver and if the new driver is flexible to the use of any forcing including e.g. daily forcings.

  • Carbon Mass Balance (from DOFOCO)
  • Topmodel - CH4 emissions (Shushi)

=> important to have the current scheme part of MICTV7 next year.

  • Yedoma soil C formation (Dan)

Dan is still improving it, and it may only be useful for paleo runs and spin-up => include it in July when Dan will have finished her PhD.

  • ORCHIDOC (Bertrand, Simon)

=> ORCHIDOC has not been tested globally and we might wait for Simon and Bertrand to do this before taking a decision in ≈ Spring 2016. This will have implications for spin up and Nitrogen. Once ORCHIDOC is shown to produce reasonable global DOC concentrations, it would make sense to merge it in MICT when merging Ronny’s DOC routing scheme.

  • DOC in river routing (Ronny / Bertrand)


Medium Term

  • Nitrogen cycle (from the TRUNK?)

=> Need to invite Daniel in the discussion. For the moment, let’s first get a branch CNP evolved from the TRUNK-N code made available by N Vuichard. Then we can decide (probably mid next year). At the moment, I would suggest to let Daniel, Shushi and Yan Sun work quietly at their pace on a CNP branch and obtain results they are satisfied with, before opting for a migration to MICT.

  • Phosphorus cycle (Daniel)

=> See above

  • Crops (Xuhui)

=> Need to invite Xuhui in the discussion. I would favor to have ORCHIDEE CROP in MICT (V7 ?) after Xuhui’s has done the new changes he wants to make in his version of ORCHIDEE CROP. We also agreed to discuss with Nicolas Vuichard about N cycle and ORCHIDEE CROP.

Long Term

  • DOFOCO (from the TRUNK)

=> related to N cycle which uses DOFOCO’s allocation and to the TRUNK strategy to eventually have DOFOCO in the TRUNK, which is challenging.

  • Analytical spinup (Philippe/Fabienne)

=> I have tried to work out the equations with matrixes but the diffusion term seems to prevent and elegant solution. I may not be good enough in the maths, but since we don’t know whether an analytical spin up is derivable, maybe we should stick to force soil plus a strict protocol to apply it.

  • Peat hydrology (Chloé)

Chloé’s code has been for now preserved « as is » in the refrigerator before she leaves. It would only make sense to decide having it in MICT or not if someone will work on it for his / her research. This should be the case of Chunjing next year. More details in Peat Hydrology.

  • Fire-permafrost, and dynamic vegetations interactions (Chao)

=> This seems to be more a research part that Chao wants to work on. Too early to decide.

  • Mosses/Shrub (from Arsène)

=> Arsène just got his first result ==> wait for the end of his PhD to decide.
