Action	Brief description	From	PI	Status end 2014 and suggestions for 2015 (ended, next step, not started... and why?)
AGRIF
AGRIF-1	Investing in AGRIF expertise	CNRS-2	Sébastien Masson
AGRIF-2	AGRIF+LIM3	CNRS-3	Simona Flavoni
AGRIF-3	AGRIF + time-splitting compatibility	MERCATOR-4	Jérôme Chanut
Config. Manager
ConfigMan?-1	Improve first version - Lead working group	MERCATOR 1	Julien Paul
ConfigMan-2	Participate to Config Manager working group	INGV-5 -	Paolo Oddo
ConfigMan?-3	Sponge layer at open boundaries	UKMO-5	Dave Storkey
ConfigMan?-4	Vertical interpolation of open boundary inputs	NOC-4	James Harle	Implemented in branch dev_r4621_NOC4_BDY_VERT_INTERP. Ready for merge when required.
System simplification
Simplification -1	Lead discussion on code simplification	CNRS-0	Gurvan Madec
Simplification -2	unused options will be removed and the non-linear free surface as default option	NOC-3	Andrew Coward	Rationalisation of LDF options achieved (branch dev_CNRS0_NOC1_LDF). Further simplification awaiting agreed implementation plans
Simplification -3	Supress LIM2 once equivalent in LIM3	CNRS-3	Martin Vancoppenolle
Simplification -4	Improvements to 1d Configuration	UKMO-8	Daley Calvert	Time constraints mean this has not happened this year. Hopefully will be done next year
Simplification -5	Improvements and Updates to OBS and ASM	UKMO-13	Multiple
Simplification -6	Masked Damping	UKMO-2	Tim Graham	Code reviewed and ready for merge. All configuration dependent options have been moved to a new tool (DMP_TOOLS).
Wave coupling
Wave-1	Wave-current interaction	INGV-4	Emanuela Clementi	in 2014 the WAVE WG met and identified, as a first step development, a set of large scale wave effects to be implemented. Some technical issues have been identified with respect to a development branch created implementing the work done by ECMWF. In 2015 the identified issues will be implemented by the WAVE WG and a proper configuration will be created to test the developments. Time will be dedicated to start discussing the second phase development identifying the coastal processes to be implemented
Wave-2	Inclusion of surface waves in NEMO	Met-Office-18	Francois-Xavier Bocquet	W.G. agreed Francois would make required changes to sbccpl. This requires other actions to be completed first so this action may be carried over
NEMO robustness
Robust- 1	Testing, validation and commissioning of recent major changes	NOC-2	Andrew Coward	Issues with stability of global configurations using full ice embedding have been partially addressed with the introduction of sub-timestepping for the vertical advection (branch dev_r4743_NOC2_ZTS) and options for coping with land-fast ice (in progress). Problems remain at the extreme Southern boundary where the ice-shelf edges are represented by sheer cliffs. The new under-shelf facility may alleviate this problem. Solutions for known problems with the iceberg option (ICB) have been collected from the community and implemented as bug-fixes to the trunk. Additional solutions for handling icebergs correctly at the north-fold and when land-only regions are suppressed are under test and will be ready for the merge. Z-tilde has undergone extensive testing in regional configurations by Jerome Chanut leading to significant improvements. Some nursing in extreme conditions (e.g. Bay of Fundy) is still required and the use of Z-tilde in global configurations cannot, yet, be recommended.
Robust-2	Ocean global configurations for next ESMs	CNRS-9	Claire Levy	In 2014, the options and parameters of ORCA1_LIM3_PISCES have been chosen and tested. Continue in 2015 on ORCA1 resolution only: - distrbution of ORCA1_LIM3_PISCES shared configuration through a specific forge/svn project at IPSL - run the forced reference experiments (climatological and interannual)
Robust-3	NEMO model reliability	INGV-2	Paolo Oddo	Continuous efforts
Robust-4	Comodo tests	CNRS-7	Simona Flavoni
ROBUST-5	BDY and biogeochemistry	CMCC-4	Tomas Lovato	it will be completed by March 2015
Robust-6	Ensure CF compliance and availability of CMIP outputs	UKMO3	Daley Calvert	Ongoing...
Robust-7	CFL diagnostics	UKMO-11	Tim Graham	Reviewed and ready to merge. Very simple code so could be added in to 3.6 release even though not critical to CMIP6?
GMD Special Issue	​http://www.geoscientific-model-development.net/submission/scheduled_special_issues.html#13	all
	GO5.0: The joint NERC-Met Office NEMO global ocean model for use in coupled and forced applications	UKMO	A. Megann	Geosci. Model Dev., 7, 1069-1092, 2014 (not in NEMO Special Issue yet)
	NEMO dynamical core	CNRS	G. Madec
	NEMO ice component	CNRS	G. Madec
