New URL for NEMO forge! http://forge.nemo-ocean.eu

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.

	1080	!! referential and grid into an atmosphere-ocean stress in
	1081	!! the (i,j) ocean referencial and at the ocean velocity point.
	1082	!! The received stress are :
	1083	!! - defined by 3 components (if cartesian coordinate)
	1084	!! or by 2 components (if spherical)
	1085	!! - oriented along geographical coordinate (if eastward-northward)

	1087	!! - given at U- and V-point, resp. if received on 2 grids
	1088	!! or at T-point if received on 1 grid
	1089	!! Therefore and if necessary, they are successively
	1090	!! processed in order to obtain them
	1091	!! first as 2 components on the sphere

	1611	!! precipitation are re-routed directly to the ocean and

	1613	!! * solid precipitation (sprecip), used to add to qns_tot
[1218]	1614	!! the heat lost associated to melting solid precipitation
	1615	!! over the ocean fraction.
[6722]	1616	!! * heat content of rain, snow and evap can also be provided,
	1617	!! otherwise heat flux associated with these mass flux are
	1618	!! guessed (qemp_oce, qemp_ice)
[1218]	1619	!!
[6722]	1620	!! - the fluxes have been separated from the stress as
	1621	!! (a) they are updated at each ice time step compare to
	1622	!! an update at each coupled time step for the stress, and
	1623	!! (b) the conservative computation of the fluxes over the

	1625	!! after the ice advection and before the ice thermodynamics,
