Since March 2022 along with NEMO 4.2 release, the code development moved to a self-hosted GitLab.
This present forge is now archived and remained online for history.

[1218]	1056	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.

[1218]	1062	!! - transform the received ocean stress vector from the received
	1063	!! referential and grid into an atmosphere-ocean stress in
	1064	!! the (i,j) ocean referencial and at the ocean velocity point.
	1065	!! The received stress are :
	1066	!! - defined by 3 components (if cartesian coordinate)
	1067	!! or by 2 components (if spherical)
	1068	!! - oriented along geographical coordinate (if eastward-northward)
	1069	!! or along the local grid coordinate (if local grid)
	1070	!! - given at U- and V-point, resp. if received on 2 grids
	1071	!! or at T-point if received on 1 grid
	1072	!! Therefore and if necessary, they are successively
	1073	!! processed in order to obtain them
	1074	!! first as 2 components on the sphere
	1075	!! second as 2 components oriented along the local grid

[1218]	1590	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
	1591	!! NB: emp_tot include runoffs and calving.

[1218]	1593	!! emp_ice = sublimation - solid precipitation as liquid
	1594	!! precipitation are re-routed directly to the ocean and
[6722]	1595	!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
	1596	!! * solid precipitation (sprecip), used to add to qns_tot
[1218]	1597	!! the heat lost associated to melting solid precipitation
	1598	!! over the ocean fraction.
[6722]	1599	!! * heat content of rain, snow and evap can also be provided,
	1600	!! otherwise heat flux associated with these mass flux are
	1601	!! guessed (qemp_oce, qemp_ice)
[1218]	1602	!!
[6722]	1603	!! - the fluxes have been separated from the stress as
	1604	!! (a) they are updated at each ice time step compare to
	1605	!! an update at each coupled time step for the stress, and
	1606	!! (b) the conservative computation of the fluxes over the
	1607	!! sea-ice area requires the knowledge of the ice fraction
	1608	!! after the ice advection and before the ice thermodynamics,
	1609	!! so that the stress is updated before the ice dynamics
