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)
Science Reviewer:
System Reviewer:
Deadline:
Priority: high
Depends on :choice of dynamic/static allocation mode
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) coupling with multi-categories ice model (coll. UKMO)

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 TRP documentation using Latex (similar to the NEMO ocean engine documentation)
(2) review of the written documentation (NOCS team)
Science Reviewer:
System Reviewer:
Deadline:
Priority:
Depends on: LOCEAN.3
Principal Investigator : Christian Ethé (Christian.Ethe@…)

LOCEAN .4 - update the IOSERVER (continuation)

Motivation: the IOser is being rewritten to sos olve performance issues .
Status : the current IOserver runs but can't we use for MPP optimization purposes
Main tasks :
if finished, integrate 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 being validated. It has been also done on LIM3 but LIM3 failed on the coarser grif
Main tasks :
implementation under svn
Science Reviewer:
System Reviewer:
Deadline:
Priority: medium
Depends on: LIM3 status
Principal Investigator : Rachid Benshila (rachid.benshila@…)

LOCEAN .7 - Suppress Lobster (continuation)

Motivation: Handle less geochemichal models for code management.
Status : Don't panic, LOBSTER will remain there, but included into PISCES
Main tasks :
(1) add LOBSTER SMS within PISCES
(2) Suppress LoBSTER directory
Science Reviewer:
System Reviewer:

Priority: low

Principal Investigator : Christian Ethé (Christian.Ethe@…)

LOCEAN -8 - 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) ORCA2-LIM3 configuration, coll. with UCL
(2) Web and paper documentations of the behaviour found
(3) Possibly reference experiment with other resolution
(4) Possibly reference experiment with ORCA2-LIM-PISCES

LEGI-9 - 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); (3) coding phase achieved for TAM phased with nemo_v3.2 & nemo_v3.2.1 (6 wks).
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) validation of 3.3 to be completed.
