Description
Create a simple testcase using OASIS to help building new coupled configurations.
Will use OASIS and a simplified fake atmosphere (TOY_ATM in OASIS wording.
May do more than only ocean-atmosphere coupling (to be discussed).
Useful as coupling demonstrator and for first level valisation of coupling with OASIS in future NEMO versions.
Details on the proposed work:
STEP 1: Implement in the up-to-date version for 2020 the test case developed in 2018
Restarting from /ccc/work/cont003/gen7451/clevy/VALID_CPL_4.0/trunk/cfgs/CPL_TOYATM in irene computer, implment the CPL_TOYATM in the up-to-date NEMO version, as a test case (in trunk/tests).
CPL_TOYATM test case description:
- Based on the ORCA2_ICE_PISCES reference configuration, activate coupling to a TOYATM (kindly offered by Eric M.) through OASIS
- coupled fields (from &namsbc_cpl namelist):
&namsbc_cpl ! coupled ocean/atmosphere model ("key_oasis3") !----------------------------------------------------------------------- nn_cplmodel = 1 ! Maximum number of models to/from which NEMO is potentially sending/receiving data ln_usecplmask = .false. ! use a coupling mask file to merge data received from several models ! ! -> file cplmask.nc with the float variable called cplmask (jpi,jpj,nn_cplmodel) nn_cats_cpl = 5 !

- The test cases needs OASIS and a simple TOYATM
- Where should the TOYATM be installed? In the test case, in NEMO tools? elsewhere?
- Validation of the test case remains to be defined more precisely (check OASIS output ATSSTSST_toyatm_01.nc compared to ocean SST ?)
STEP 2: is this the final version of the expected test case?
- Adding other couplings?
- Checking sea-ice?
STEP 3: implement final test case
Implement the finalised test case as part of the usual validation testbed, and also in the github for NEMO test cases
