| | 12 | == Major improvements |
| | 13 | |
| | 14 | === New physics and numerics |
| | 15 | |
| | 16 | * New pressure gradient suitable for s-coordinate (namelist ln_hpg_djc) |
| | 17 | * Completion of Griffies iso-neutral diffusion (ln_traldf_grif) |
| | 18 | * Back to a semi-implicit bottom friction (bugfree) (namelist ln_bfrimp) |
| | 19 | * Add Pacanowski-Philander scheme for computation of Ekman depth in zdfri |
| | 20 | * Add a new bulk formulae (namelist ln_blk_mfs and &namsbc_mfs) |
| | 21 | * Introduce a drag coefficient compute by wave model (new namelist &namsbc_wave) |
| | 22 | * Add tidal potential forcing (new namelist &nam_tide) |
| | 23 | * Neptune effect parametrization |
| | 24 | * Point to point MPI communication for north fold (namelist ln_nnogather) |
| | 25 | * Allow sub timestepping for biogeochemistry models when using non-linear free surface |
| | 26 | * Improvement in PISCES (light limitation ; quota model for iron ; use Pa in gas exchange ; fldread for all data ; calcite dissolution & calcon salinity dependence) |
| | 27 | |
| | 28 | === Configurations, diagnostics and tools |
| | 29 | |
| | 30 | * Suppression of POMME configuration |
| | 31 | * Addition of a regional configuration AMM12 (key_amm_12km and [http://prodn.idris.fr/thredds/catalog/ipsl_public/reee451/NEMO/catalog.html?dataset=DatasetScanipsl_public/reee451/NEMO/amm12_inputs_v3_4.tar input files]) |
| | 32 | * Improvement of format for lagrangian floats |
| | 33 | * Online computing of transport across sections |
| | 34 | * Tidal harmonic analysis (new namelist &nam_diaharm) |
| | 35 | * Tools to prepare input files for observation operator |
| | 36 | * Timing functionality (namelist ln_timing) |
| | 37 | |
| | 38 | === System simplification |
| | 39 | |
| | 40 | * Simplification of dynamic allocation |
| | 41 | * End of merge TRA/TRA (no more separate 3d arrays for tracers, only 4d) |
| | 42 | * Suppression of obsolete hpg options |
| | 43 | * More flexible definition of BDY input data |
| | 44 | * Simplification of interfaces toward biogeochemical models |
| | 45 | * Interface with CICE in coupled mode |
| | 46 | * Use of fldread to read/interpolate data for passive tracers and dynamical input data for OFFLINE configurations |
