LOCEAN .1 - MPP evolution (continuation)

Motivation: Improve the mpp behaviour of NEMO by playing with width of the overlap area, the number of communication,
Status : We are now using 1 point overlap area. Possibility to use more exists but is not compatible with the North Fold condition
Main tasks :
(1)switch to a 2 points with overlap area
(2)suppress useless communication (there should be only 2 for the internal mode)

Priority: high

Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN .2 - Coupled interface (continuation)

Motivation: The current coupled surface module only work with LIM2. Its functionality should be extended to the cases where sea ice is not used (for example with region coupled configuration), and where a multi category sea-ice component is used (LIM3 or CICE).
Status : Preliminary work has been done for CICE
Main tasks :
(1) documentation of the coupled surface module
(2) help UCL to implement and test LIM3 case

Priority:
Depends on: collaboration with UKMO
Principal Investigator : Sebastien Masson (smasson@…)

LOCEAN .3 - reference manuels (continuation)

Motivation: paper documentation a never-ending story (dixit G. Madec)
Status :
Main tasks :
(1) Create the TOP documentation (TRP + interface to bio-model) using Latex (similar to the NEMO ocean engine documentation)
(2) review of the written documentation (NOCS team)

LOCEAN .4 - update the IOSERVER (continuation)

Motivation: the IOser is being rewritten to solve performance issues .
Status : the current IOserver runs but can't we use for MPP optimization purposes
Main tasks : integrate, debug and benchmark the new version
Science Reviewer:
System Reviewer:
Deadline:
Priority:
Depends on: work done on new IOserver at IPSL
Principal Investigator : Sebastien Masson (smasson@…)

LOCEAN .5 - new vertical coordinate (continuation)

Motivation: introduce an arbitrary lagrangian eulerian coordinate to reduce spurious diapycnal mixing due to high frequency vertical variations
Status : done in a phd thesis, see Leclair 2010
Main tasks : update for the new NEMO version

LOCEAN .6 - Agrif on sea-ice (continuation)

Motivation: Be able to use AGRIF on high latitude region .
Status : Development has been done for LIM2-VP and LIM2_EVP and is validated.
Main tasks :
(1) Validate the LIM3 case
(2) improve the robustness of AGRIF/sea-ice (portability issue)
(3) Add a documentation

System Reviewer:
Deadline:
Priority: medium
Depends on: LIM3 status
Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN -7 - ORCA2-LIM based on NEMO (continuation)

Motivation: Provide to all groups using NEMO in coupled O/I/A simulations a reference set of forced experiments that document the effect of various physical package as well as the changes from the OPA8 to NEMO with respect to the ocean and ice components (and possibly PISCES). This is part of the IsENES EU project.
Status : ORCA2-LIM2 configuration (bathy, physics) has been updated, and Standard output for IPCC runs using IOM(v3.2). An environment has been developed to run long forced and coupled experiments together with the creation of standard control plots. Simulations have been performed (reference CORE2 normal year and interannual simulations )
Main tasks :
(1) achieve ORCA2-LIM3 configuration, coll. with UCL ; ORCA2-CICE configuration, coll. with NOCS
(2) Web and paper documentations of the behaviour found

LEGI-8 - Development of TAM (continuation)

Motivation: development of the Tangent and Adjoint Model (TAM) of NEMO.
Status : Grenoble action (LJK, LEGI, ANR VODA), a 3 year project started in 2008, and well engaged: (1) first release of tangent linear and adjoint model phased with nemo_v3_3 , ocean dynamics, which includes ORCA2_Z31, GYRE_Z31 configurations, MPP capabilities and documentation (2) validation tools available (adjoint test, tangent linear hypothesis)
main tasks :
(1) include Grenoble validation tools in the SETTE settings: SETTE workshop required.
(2) create tutorial, test cases and reference experiment for Adjoint (4 wks - nemo_v3_3 ).
(3) organise the review cycles for nemotam.
(4) phasing and validation with v3.3

LOCEAN .9 - Rotated bilaplacian

Motivation: Rotated biharmhonic diffusion operator. This we would  be able to use it in the isopycnal direction, and this operator would also be particularly suitable for s-coordinate 
Status : Implemented in ROMS (UCLA) by F. Lemarié et al. (Ocean Modeling in press)
Main tasks :
(1) adaptation to NEMO
(2) test phase and documentation
Science Reviewer:

Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN .10 - KPP scheme

Motivation: KPP (K profile parametrization is widely used in ocean models to compute vertical mixing coefficients. Current version implemented in NEMO is old and unmaintained, furthermore, KPP has been redesigned for ROMS model to improve the regularity of the solution (better numerics)
Status : Implemented in ROMS (UCLA) by F. Lemarié et al. (Ocean Modeling in press)
Main tasks :
(1) adaptation for NEMO
(2) test phase and documentation

LOCEAN .11 - Compact vertical advection scheme

Motivation: Compact schemes have the particularity to be of high order but compact in space
Status : Developed for NEMO version 3.1 (L. Debreu)
Main tasks :
(1) adaptation to v3.3
(2) validation and documentation

LOCEAN .12 - Energy diagnostics

Motivation: output 3D trends of tracers, momentum, kinetic energy and potential energy.
Status : the extraction of trends terms exists, but not the 3D output of the trends
Main tasks :

(1) implement the 3D output of tracers and momentum trends
(2) compute and output the 3D trends of PE and KE
(3) validatation + documentation

LOCEAN .13 - Configuration definition

Motivation: Be able to define configurations from namelist[BR]] Status : Currently a par_xxx.h90 needs to be created when adding a new configuration
Main tasks :
(1) propose possible solutions, create a working group if people interested
(2) propose an approach for 2012 dev comm
