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   !  Number of sea ice categories over which coupling is to be carried out (if not 1)

The test cases needs OASIS and a simple TOYATM
Where should the TOYATM be installed? In the test case, in NEMO tools? elsewhere?
