The new release 3.4 of NEMO is now available.
Note this is a major release and the documentation has been updated in consequence.
Major improvements
New physics and numerics
- New pressure gradient suitable for s-coordinate (namelist ln_hpg_djc)
- Completion of Griffies iso-neutral diffusion (ln_traldf_grif)
- Back to a semi-implicit bottom friction (bugfree) (namelist ln_bfrimp)
- Add Pacanowski-Philander scheme for computation of Ekman depth in zdfri
- Add a new bulk formulae (namelist ln_blk_mfs and &namsbc_mfs)
- Introduce a drag coefficient compute by wave model (new namelist &namsbc_wave)
- Add tidal potential forcing (new namelist &nam_tide)
- Neptune effect parametrization
- Point to point MPI communication for north fold (namelist ln_nnogather)
- Allow sub timestepping for biogeochemistry models when using non-linear free surface
- Improvement in PISCES (light limitation ; quota model for iron ; use Pa in gas exchange ; fldread for all data ; calcite dissolution & calcon salinity dependence)
Configurations, diagnostics and tools
- Suppression of POMME configuration
- Addition of a regional configuration AMM12 (key_amm_12km and input files)
- Improvement of format for lagrangian floats
- Online computing of transport across sections
- Tidal harmonic analysis (new namelist &nam_diaharm)
- Tools to prepare input files for observation operator
- Timing functionality (namelist ln_timing)
System simplification
- Simplification of dynamic allocation
- End of merge TRA/TRA (no more separate 3d arrays for tracers, only 4d)
- Suppression of obsolete hpg options
- More flexible definition of BDY input data
- Simplification of interfaces toward biogeochemical models
- Interface with CICE in coupled mode
- Use of fldread to read/interpolate data for passive tracers and dynamical input data for OFFLINE configurations
