New URL for NEMO forge!   http://forge.nemo-ocean.eu

Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

MERCATOR.1 — resolving the 2 versions of time-stepping

Motivation: Tracer conservation and time splitting. reference: Shchepetkin, A. F., and J. C. McWilliams?, 2005
Status :Running in NEATL36 at Mercator.
main tasks : Main idea:replace Leapfrog scheme by a Fb tamporal scheme, but keep actual method for updating ssh at 3D time-stepping.
workplan:
1.test some eventual problem of divergence of SSh in barotropic mode compared to SSH in 3d mode ( cf Hallberg and Adcroft, OM 2009: Reconciling estimates of the free surface height in Lagrangian vertical coordinate ocean models with mode-split time stepping).
2.implementation in NEMO_3.3 of this time-splitting.
3.test in high-resolution configuration at Mercator.
4.take a decision for reorganization of step for time-splitting.
Priority: High
Principal Investigator : Clement Bricaud & Jerome Chanut (jchanut@…)
Number of weeks : 4 (TBC)


MERCATOR.2 — exploration of implicit bottom friction

Motivation: Use NEMO standard implicit bottom friction in Mercator Regional configuration ( z-coord ).

Status :
main tasks :
Principal Investigator : Jerome Chanut (jchanut@…)
Priority: high

Number of weeks : 2 (TBC)


MERCATOR.3 — Solar flux filtering at daily frequency to force biogeochemistry model.

Motivation: For coupled model ( physic + bio ): physic needs 24 hours (+ diurnal cycle) or 3 hours solar fluxes, but bio need a 24 hours mean.
Status : End of 2012 task

MERCATOR.4 — Implementation of a configuration manager

Motivation: Add a configuration manager
Status :
main tasks :

. upgrade SIREN (now beased on NEMO2.3) to make it suitable with new release of NEMO :
. new classication tree
. use makenemo (FCM tools ?)
. change name management. now SIREN is based on Mercator naming:So it will be helpfull, if each member of the NEMO consortium could send me some output of their models (Bathymlertry, coordinates, and 1 or 2 days of outputs)
. improve error management.
. use gridgen tools.
. get file from opendap.
. use weight tools
