[WP2022 PHYS - NOC] Add GEOMETRIC parameterisation

Add GEOMETRIC parameterisation

GEOMETRIC parameterisation from Julian Mak; to be ported from v4.0 code. This is a completed and published development that is available from a user’s personal repository. The code just needs to be updated to 4.2 compatibility and tested.

GEOMETRIC is an approach to representing the unresolved turbulent eddies in ocean climate models. and is well introduced here.

Code implementation

  • Most new code is contained within a new routine: OCE/LDF/ldfeke.F90
  • New source terms are computed in OCE/DYN/dynldf_lap_blp.F90
  • The rest is housekeeping (new namelist entries; new diagnostics etc.)

At 4.0.6 the changes were confined to:

OCE/nemogcm.F90
OCE/DYN/dynldf_lap_blp.F90
OCE/LDF/ldfeke.F90
OCE/LDF/ldftra.F90
OCE/step.F90
OCE/DIA/diawri.F90
OCE/step_oce.F90
OFF/nemogcm.F90

expect minor variations on this at 4.2.x

To be SETTE tested in ORCA2_ICE_PISCES and passed back to the author for more careful testing.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
