UKMO.2 — Providing capability to run NEMO with CICE (v3.4)

Motivation: Useful for comparing sensitivity to different sea ice models
Status : Dependent on LIM3 work (see A.5 above).
Main tasks : (4 wk)
(1) Add code to allow running of NEMO-CICE stand-alone model. (2w)
(2) Allow sbccpl interface to work with CICE (particularly multi-category fields). (2w)

UKMO.3 — Providing OBS and ASM functionality (v3.4)

Motivation: Allows NEMOVAR to be run as well as using the tools for validation
Status : Some work done; further developments on-going.
Main tasks : (10 wk)
(1) Make branches of NEMO so that the NEMOVAR version of OBS and ASM code are split up and made separate to any other changes.
(2) Update the OBS and ASM branches from vn3.0 to the latest Paris trunk version.
(3) Run the standard NVTK tests.
(4) Supply the OBS and ASM code to NEMO systems team.
(5) Develop test environments for OBS and ASM.
(6) Collate documentation for OBS and ASM and pass to systems team.
(7) Help coordinate developments to the IAU code so that the changes from Charles-Emmanuel Testut go into the NEMO base code.
(8) Add ability to ingest drifter data to the OBS for validation purposes

UKMO.4 — Mixed laplacian-bilaplacian diffusion (v3.3)

Motivation : Addition of a mixed laplacian/bilaplacian lateral diffusion on momentum scheme. Also allowing the choice of neither scheme for testing purposes.
Status : Code written and running at vn3.0.
Main tasks : (1 wk)
(1) Update to latest version of NEMO.
(2) Finalise testing of mixed scheme and return to trunk with testing and documentation.

UKMO.8 — GODAE metrics (v3.3)

Motivation: Test the meridional heat transport and overturning circulation diagnostic of the GODAE metrics
Status : Code working in 3.0 but still requires some tidying up and updating to 3.2.
Main tasks : (1 w)
(1) In collaboration with Mercator decide on a final version of metrics for inclusion

UKMO.10 — NVTK upgrade (v3.3)

Motivation: Get NVTK working at UKMO. And with FCM for extract and build.
Status : NVTK doesn't work on IBM; FCM work not started
Main tasks : (8 w)
(1) Investigate feasibility of using FCM for extract and build (2) Get NVTK working on the Met Office IBM system
(3) If feasible, setup using FCM for extract and build - if not feasible we will advise Paris on restructuring required for it to be feasible
Principal Investigator : Richard Hill
Deadline : 1 October 2010
Priority: High
Science Reviewer : Not required
System Reviewer : Rachid Benshila (TBC)

UKMO.11 — Vertical PPM scheme (v3.3)

Motivation: The ppm is a 3rd order advection scheme with property of monotonicity. It could be superior over the existing 3 available vertical advection schemes in NEMO (cen2, muscl, and tvd), at least in the sense that it is one order higher. We will add an option to invoke the vertical PPM under the configurations of all the 6 available horizontal advection schemes in NEMO. As long as the horizontal advection doesn't exhaust a 3-d cell, the vertical ppm can even work with Courant Number > 1. This will be a good property for the s-coordinate. Also, it is good for the calculation of the advection of a discontinous field, such as thermocline, front.

Status : Scoping of work has started but implement has not
main tasks : Code design, implementation, testing and documentation (4wk)
