Description
Revisit the formulation of the fluxes between ocean, ice and atmosphere : an exchange of water (mass exchange) is now explicitly associated with an exchange of heat and salt content. This modification simplifies the implementation of a fully embedded sea-ice.
The main modifications concern OPA, LIM2 and LIM3. They are:
(1) the introduction in LIM2 and LIM3 of the heat and salt content exchanged with the ocean
(2) the suppression of emps by introducing fsalt, the salt flux at the ocean surface (only non zero below sea-ice)
(3) the modification of the definition of qns : the non solar part of the surface heat flux takes now also into account the heat content changes due to the change in volume associated with evaporation, precipitation, ice freezing and ice melting.
(4) the modification of trasbc module in order to take into account the above changes
This update is the NOCS.4 task (Revisit of mass and salt fluxes) due by 2nd July 2010

Still some stability questions when running the LIM2-EVP, ORCA2 test-case with full embedding. Works with reduced (halved) timestep. Still investigating. |

Stage 1a of 2012 development: correcting possible bug in sbccpl.F90 and reverting to use of instantaneous sst value in preference to the mean value (sst_m) in case coupling frequency differs from the nn_fsbc frequency. |

Stage 1 of 2012 development: porting of changes on old development branch (2011/DEV_r1837_mass_heat_salt_fluxes) into new branch. Corrected a few errors on the way. This branch now compiles but is incomplete. Still missing LIM3 changes which must reside on a certain persons laptop somewhere |
| 3386 | acc | 2012-05-09T18:52:31+02:00 | Create development branch for the latest implementation of the NOCS development to tidy up the heat and mass fluxes to and from the ocean. This is a necessary precursor to correct embedding of the ice in the ocean and revisits work done (but not finished) in previous years. See ticket #665 |

This revisit together with the embedment of the sea-ice has been done in 2012. See the development in the dev_r3385_NOCS04_HAMF branch. It has been included in dev_UKMO_2012 so it will be part of the forthcoming v3.5alpha
