NOCS.01 - User Interface
Provide support to users of NEMO. NOC will provide in depth support for code supplied by them.
Motivation: Shared daily support to users, web & paper documentation.
Main task: (2 wk)
Principal Investigator : Andrew Coward/Steven? Alderson (acc@…)
NOCS.02 - System maintenance
(a) Code Reviewing - Reviewing code from NEMO partners (2 w)
(b) Beta Testing - Beta testing of new versions (4 w)
(c) Collaboration - Time spent:
- hosting visitors from partner institutes on the NEMO system team
- travelling to partner institutes for exchange visits
- attending NEMO Steering, Developers and System Team meetings
- attending “merge party”
(2 w)
Principal Investigator : Steven Alderson (sga@…)
NOCS.03 — Prather advection
Motivation: The Prather advection scheme is currently the advection scheme of choice in other key modelling systems (MOM, ROMS etc.)
Main task: (3 wk)
(1) Implementation in the trunk+ NVTK + documentation (3 wk) v3.4 release
Principal Investigator : Andrew Coward/George? Nurser (acc@…)
Deadline : 22nd April 2011
Priority: Medium
Science Reviewer : Gurvan Madec (TBC)
System Reviewer : Rachid Benshila (TBC)
NOCS.04 — Revisit of mass and salt fluxes (end)
Motivation: As a consequence of the embedding of sea-ice into the ocean (see NOCS.5), the total mass of salt of the combined sea-ice/ocean system is conserved by removing a volume of water from the ocean when ice forms or adding a volume of water when it melts. When ice forms, salt contained in the water is returned to the ocean, less the salt retained in the ice itself. When ice melts, the salt contained is added back to the ocean.
Status: Implemented in 2010 but not finalised before the end of year merge. Code refresh and re-validation required.
Main task: (2 wk)
(1) Implementation in the trunk+ NVTK + documentation (2 wk) v3.4 release
Principal Investigator : Gurvan Madec (@noc.soton.ac.uk)
Deadline : 2nd February 2011
Priority: High
Science Reviewer : Chris Harris (TBC)
System Reviewer : Rachid Benshila (TBC)
NOCS.05 — Embedded sea-ice (including CICE)''' (end)
Motivation: Introduce fully embedded sea-ice (i.e. with sea-ice loading applied to the ocean) (Campin et al. OM 2008)
Status: Implemented in 2010 but not finalised before the end of year merge. Code refresh and re-validation required. The existing scheme to embed LIM2 and LIM3 will also be extended to include CICE (subject to the CICE interface entering the system)
Main task: (4 wk)
(1) Re-implement LIM2/3 solution into v3.3 + NVTK + documentation (3 wk) v3.4 release
(2) Extend solution to include CICE (subject to availability of finished interface) (2 wk) v3.4 release
Principal Investigator : Gurvan Madec/Steven? Alderson/Yevgeny? Aksenov (yka@…)
Deadline : 2nd September 2011
Priority: High
Science Reviewer : Chris Harris (TBC)
System Reviewer : Rachid Benshila (TBC)
NOCS.06 — Eden and Greatbatch eddy parameterisation
Motivation: To provide an alternative to the default Held and Larichev scheme
Status: Ready to proceed
Main task: (2 wk)
(1)
(2)
Principal Investigator : George Nurser (agn@…)
Deadline : 4th March 2012
Priority: High
Science Reviewer : Mercator (TBC)
System Reviewer : Rachid Benshila (TBC)
NOCS.07 — Rationalisation of support for ORCA configurations (including independence of vertical resolution) '''
Motivation: A cleaning and enhancement of code support for global (ORCA) configurations is required to introduce configurations in common use across the community.
Main task: (4 wk)
(1) Support will be improved or added for ORCA1, ORCA05, ORCA025 and ORCA_R12 configurations in such a way that multiple vertical resolutions of each can be maintained.
(2) The use of .h90 files will also be suppressed.
Principal Investigator : Andrew Coward (acc@…)
Deadline : 19th August 2011
Priority: Medium
Science Reviewer : Not needed
System Reviewer : Paris (TBC)
NOCS.08 — Time stepping of vertical diffusion
Motivation: An improvement in the numerical treatment of vertical diffusion can be achieved by replacing the fully implicit scheme with a Crank-Nicholson scheme. This approach is widely used in other ocean models (e.g. ROMS, MARS...) and can be implemented relatively simply.
Main task: (1 wk)
(1) The replacement scheme will be implemented and its performance tested.
Principal Investigator : Andrew Coward (acc@…)
Deadline : 18th February 2011
Priority: Medium
Science Reviewer : Mercator (TBC)
System Reviewer : Paris (TBC)
NOCS.09 — Implementation of spectral nudging
Motivation: Work by our Canadian colleagues has demonstrated the potential benefits of spectral nudging techniques to restore large scale gradients without suppressing meso-scale activity.
Status: Coded in v3.2. Requires porting to and testing and documenting in v3.4
Main task (3 wk)
Deadline : 22nd April 2011
Priority: High
Science Reviewer : Mercator (TBC)
System Reviewer : Paris (TBC)
Principal Investigator : Jeff Blundell (jeff@…)
NOCL.01 — Wetting and Drying
Motivation: Add Wetting/Drying? functionality to NEMO for coastal ocean applications
Status: In preparation
Main task (26 wk)
Deadline : End of 2012
Priority: Medium
Science Reviewer : TBC
System Reviewer : TBC
Principal Investigator : Hedong Liu (heau@…) + ???
NOCL.02 — Smagorinsky viscosity
Motivation: Add Samgorinsky viscosity/diffusivity method
Status: Coded in v3.2 but need further modification and testing
Main task (? wk)
Deadline :
Priority: Medium
Science Reviewer : TBC
System Reviewer : TBC
Principal Investigator : Maria Luneva (mane1@…)
NOCL.03 — Vertical PPM advection scheme
Motivation: Add vertical PPM option to the existing advection scheme setup
Status: Coded in v3.2 but need further debugging and testing
Main task (4 wk)
Deadline : End of Jan, 2010
Priority: High
Science Reviewer : Mercator(TBC)
System Reviewer : Paris(TBC)
