| | 4 | = Summary by Nicolas Vuichard on the current status and ongoing actions : 23 Nov 2018 |
| | 5 | |
| | 6 | What has been done the last 2 weeks ? |
| | 7 | |
| | 8 | - About the model (https://forge.ipsl.jussieu.fr/orchidee/browser/branches/ORCHIDEE-CN) |
| | 9 | + Update of the branch based on the latest trunk version (commit 5578 : https://forge.ipsl.jussieu.fr/orchidee/changeset?reponame=&new=5578%40branches%2FORCHIDEE-CN&old=5569%40branches%2FORCHIDEE-CN) |
| | 10 | + Add the possibiliy of reading a 2D leaf CN map for being use with the IMPOSE_CN conifugaration (commit 5562 : https://forge.ipsl.jussieu.fr/orchidee/changeset?reponame=&new=5562%40branches%2FORCHIDEE-CN&old=5538%40branches%2FORCHIDEE-CN) |
| | 11 | + Update of the default parametrization using the latest run.def file used for ORCHIDEE-CN (commit 5590 : https://forge.ipsl.jussieu.fr/orchidee/changeset?reponame=&new=5590%40branches%2FORCHIDEE-CN&old=5589%40branches%2FORCHIDEE-CN) |
| | 12 | + The term of respiration associated to an excess of carbon in the labile or reserve pool is output separately (commit 5620 : https://forge.ipsl.jussieu.fr/orchidee/changeset?reponame=&new=5620%40branches%2FORCHIDEE-CN&old=5606%40branches%2FORCHIDEE-CN). All output variables with Growth (like RESP_GROWTH or rGrowth) are duplicated, with Excess "instead" of "Growth" in the output name. |
| | 13 | |
| | 14 | - About the configurations used for running the model: |
| | 15 | + A svn branch has been created for versioning these configurations prior to move them on the trunk (https://forge.ipsl.jussieu.fr/orchidee/browser/branches/ORCHIDEE-CN_CONFIG) |
| | 16 | + In particular, we can now use FG1 (SPINUP_ANALYTIC_FG1 config), FG1trans (OOL_SEC_STO_FG1trans config) and FG2 (OOL_SEC_STO_FG2 config) for global runs and ENSEMBLE configuration for in-situ simulations at fluxnet stations. |
| | 17 | |
| | 18 | What could be done based on these developments ? |
| | 19 | + Developments related to the Permafrost done by Bertrand could be updated with the latest version of ORCHIDEE-CN and commited (if every is working when the flag for permafrost is set to "no"). @Bertrand: At first, you may try to copy your local repository of ORCHIDEE-CN with your modifications and to do a 'svn update'. Let us (Josefine + me) if you need help for that. |
| | 20 | + Check the parameter values of the ORCHIDEE-CN version: prior commit 5590, several parameters were set in the run.def, in particular for N-related and CAN-related parameters. These values correspond to those from the first run.def I got from ORCHIDEE-DOFOCO or to changes we have done over time on the ORCHIDEE-CN branch. You (in particular Sebastiaan) may look at these values that are now set as default values in the code by looking at this diff between r5589 and r5590). |
| | 21 | + Still about the change in parametrization, and in particular about some changes done recently in the trunk : if these parameters still exist in ORCHIDEE-CN, the changes have been accounted for when we have updated the branch with the trunk. If the parameters do not exist anymore but have still a significance nothing has been done so far. Maybe there are more parameters but i have at least these 2 params in mind: carbon_tau_ipassive and carbon_tau_islow. They have changed on the trunk, the parameters do not exist anymore in ORCHIDEE-CN, they have been replaced by : som_turn_islow and som_turn_ipassive (=1/carbon_tau) but their values have not been changed in ORCHIDEE-CN. Maybe there are other parameters like those two... We may want to check that. |
| | 22 | + Re-running test simulations for the grassland sites (Fabienne I guess you are ok for continuing that action with the updated version ?) |
| | 23 | + Performing a set of global simulations FG1, FG1trans, FG2 with the latest version of ORCHIDEE-CN. Vlad, could you be in charge of these simulations. Please, if you need help or advice, come to see me. |
| | 24 | + Maintaining a wiki page for documenting the work arount ORCHIDEE-CN (I don't think I'm good for that): https://forge.ipsl.jussieu.fr/orchidee/wiki/DevelopmentActivities/CMIP6/DevelopmentsCMIP6/V2/Nitrogen. Philippe could help for that action ? |
| | 25 | |
| | 26 | Practically, how to get the model version and the configuations ? |
| | 27 | + Download modipsl |
| | 28 | + Replace the 2 following lines in the mod.def file for ORCHIDEE_trunk config for instance: |
| | 29 | #-C- ORCHIDEE_trunk trunk/ORCHIDEE HEAD 14 ORCHIDEE modeles |
| | 30 | #-C- ORCHIDEE_trunk trunk/ORCHIDEE_OL HEAD 14 ORCHIDEE_OL config |
| | 31 | by |
| | 32 | #-C- ORCHIDEE_trunk branches/ORCHIDEE-CN HEAD 14 ORCHIDEE modeles |
| | 33 | #-C- ORCHIDEE_trunk branches/ORCHIDEE-CN_CONFIG HEAD 14 ORCHIDEE_OL config |
| | 34 | + Download the model by "./model ORCHIDEE_trunk |
