2009 Stream 0 : coupled ready

The object of this stream is to ensure that the whole system is “coupled ready”. To precede the dead line of the next IPCC exercise, a validated generic coupling interface must be introduced in the system by the middle of 2009. This interface intends to be shared by all groups involved in coupled studies (IPSL, Met Office, GEOMAR-kiel, Meteo France, CERFACS, INGV, EC-Earth, …). In addition, the improvements in the physics of the global ocean that has been made in the research community during the last few years have to be offered to all users (see Stream 4.1). The actions of the stream are:

Substream 0.1 : Coupling interface

Description and participants

Generic coupling interface including LIM3 and CICE Introduce in NEMO an OASIS interface that can be used with the main European atmospheric models (ARPEGE, ECHAM, HadAm?, LMDz) and works with LIM2, LIM3 and CICE ice models.
Work:
(1) achieve the generic coupled interface (5 w) (v3.2)
(2) adapt the interface to LIM3 (3 w) (v3.2)
(3) adapt the interface to HadGAM and CICE (5 w) (v3.2)

Advancement

(1) done, ready vor v2.3
(2)
(3) CICE-related details in #436

Substream 0.2 : ORCA2-LIM

Description and participants

Provide to all groups starting 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).
Work :

(1) Updated ORCA2-LIM2 configuration (bathy, CORE climatologic forcing) (v3.2)
(2) Updated physics for ORCA2-LIM2 (cf. S4.1 and S4.2e) (v3.2)
(3) ORCA2-LIM3 configuration (v3.2)
(4) CF compliance of all NEMO NetCDF outputs (2 w) (v3.2)
(4) Standard output for IPCC runs using IOM (v3.2)
(5) Standard plots using libIGCM library (IsENES) (v3.3)
(6) Reference forced simulations with a mean seasonal cycle over 2,000 years (v3.3)
(7) Reference forced simulations with a 1958-2004 interannual forcing. (v3.3)
(8) A series of runs (starting from the NEMO physics down to OPA8 physics not necessary all with both mean seasonal and interannual forcing. (v3.3)
(9) Web and paper documentations of the behaviour found (v3.3)
(10) Possibly reference experiment with other resolution (ORCA1, 05, 025…) (v3.X)
(11) Possibly reference experiment with ORCA2-LIM-PISCES (v3.X)

Advancement

(1) Updated ORCA2-LIM2 configuration (bathy, CORE climatologic forcing) (v3.2) : underway
(2) Updated physics for ORCA2-LIM2 (cf. S4.1 and S4.2e) (v3.2) : underway
(3) ORCA2-LIM3 configuration (v3.2)
(4) CF compliance of all NEMO NetCDF outputs (2 w) (v3.2)
(4) Standard output for IPCC runs using IOM (v3.2)
(5) Standard plots using libIGCM library (IsENES) (v3.3)
(6) Reference forced simulations with a mean seasonal cycle over 2,000 years (v3.3) : ok
(7) Reference forced simulations with a 1958-2004 interannual forcing. (v3.3)
(8) A series of runs (starting from the NEMO physics down to OPA8 physics not necessary all with both mean seasonal and interannual forcing. (v3.3)
(9) Web and paper documentations of the behaviour found (v3.3)
(10) Possibly reference experiment with other resolution (ORCA1, 05, 025…) (v3.X)
(11) Possibly reference experiment with ORCA2-LIM-PISCES (v3.X)

Substream 0.3 : CICE

Description and participants

Introduce in the NEMO reference code an interface to CICE ice model. Work: (1) document the interface and introduce it in NEMO (5 w) (v3.2)
