Current status
Version 3.4 is currently a beta release (since 2011/12/22), so any feedback is welcome. The trunk version stil contains a stable version of 3.3.1
An extensive review of the changes included in the 3.4_beta can be found here http://forge.ipsl.jussieu.fr/nemo/report/44
Documentation has been updated accordingly and is available there http://forge.ipsl.jussieu.fr/nemo/browser/branches/2011/dev_NEMO_MERGE_2011/DOC/NEMO_book.pdf
Practical informations
The beta version doesn't correspond to a given tag but is located on a svn branch dev_NEMO_MERGE_2011 which can be browsed there http://forge.ipsl.jussieu.fr/nemo/browser/branches/2011/dev_NEMO_MERGE_2011.[[BR]]
In practice, the initial version of the beta was revision 3237 on this branch. You will be able to update the beta by performing svn update under the root repository.
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) #867 (namelist ln_bfrimp)
- add Pacanowski-Philander scheme for computation of Ekman depth in zdfri wiki:ticket851?
- add a new bulk formulae wiki:ticket/850? (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)
- Netpune effect parametrization #843
- point to point MPI communication for north fold (namelist ln_nnogather)
- allow sub timestepping for biogeochemistry models when using non-linear free surface wiki:ticket/855?
- 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 http://dodsp.idris.fr/reee512/NEMO/amm12_inputs_v3_4.tar)
- improvement of format for lagrangian floats wiki:ticket/859?
- online computing of transport across sections wiki:ticket/864?
- tidal harmonic analysis (new namelist &nam_diaharm)
- tools to prepare input files for observation operator wiki:ticket/869?
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 wiki:2011WP/2011Stream2/OpenBoundaryProgress2011
- simplification of interfaces toward biogeochemical models wiki:ticket/846?
- interface with CICE in coupled mode wiki:ticket/662?
- Use of fldread to read/interpolate data for passive tracers and dynamical input data for OFFLINE configurations
