[1218]	935	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
	936	!! provide the ocean heat and freshwater fluxes.
[888]	937	!!
[1218]	938	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
	939	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
	940	!! to know if the field was really received or not
[888]	941	!!
[1218]	942	!! --> If ocean stress was really received:
[888]	943	!!
[1218]	944	!! - transform the received ocean stress vector from the received
	945	!! referential and grid into an atmosphere-ocean stress in
	946	!! the (i,j) ocean referencial and at the ocean velocity point.
	947	!! The received stress are :
	948	!! - defined by 3 components (if cartesian coordinate)
	949	!! or by 2 components (if spherical)
	950	!! - oriented along geographical coordinate (if eastward-northward)
	951	!! or along the local grid coordinate (if local grid)
	952	!! - given at U- and V-point, resp. if received on 2 grids
	953	!! or at T-point if received on 1 grid
	954	!! Therefore and if necessary, they are successively
	955	!! processed in order to obtain them
	956	!! first as 2 components on the sphere
	957	!! second as 2 components oriented along the local grid
	958	!! third as 2 components on the U,V grid

	1366	!! - given at U- and V-point, resp. if received on 2 grids
	1367	!! or at a same point (T or I) if received on 1 grid

[6722]	1563	!! ** Purpose : provide the heat and freshwater fluxes of the ocean-ice system
[1218]	1564	!!
	1565	!! ** Method : transform the fields received from the atmosphere into
	1566	!! surface heat and fresh water boundary condition for the
	1567	!! ice-ocean system. The following fields are provided:
[6722]	1568	!! * total non solar, solar and freshwater fluxes (qns_tot,
[1218]	1569	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
	1570	!! NB: emp_tot include runoffs and calving.
[6722]	1571	!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
[1218]	1572	!! emp_ice = sublimation - solid precipitation as liquid
	1573	!! precipitation are re-routed directly to the ocean and
[6722]	1574	!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
	1575	!! * solid precipitation (sprecip), used to add to qns_tot
[1218]	1576	!! the heat lost associated to melting solid precipitation
	1577	!! over the ocean fraction.
[6722]	1578	!! * heat content of rain, snow and evap can also be provided,
	1579	!! otherwise heat flux associated with these mass flux are
	1580	!! guessed (qemp_oce, qemp_ice)
[1218]	1581	!!
[6722]	1582	!! - the fluxes have been separated from the stress as
	1583	!! (a) they are updated at each ice time step compare to
	1584	!! an update at each coupled time step for the stress, and
	1585	!! (b) the conservative computation of the fluxes over the
	1586	!! sea-ice area requires the knowledge of the ice fraction
	1587	!! after the ice advection and before the ice thermodynamics,
	1588	!! so that the stress is updated before the ice dynamics
	1589	!! while the fluxes are updated after it.
[1218]	1590	!!
[6722]	1591	!! ** Details
	1592	!! qns_tot = pfrld * qns_oce + ( 1 - pfrld ) * qns_ice => provided
	1593	!! + qemp_oce + qemp_ice => recalculated and added up to qns
	1594	!!
	1595	!! qsr_tot = pfrld * qsr_oce + ( 1 - pfrld ) * qsr_ice => provided
	1596	!!

	1598	!! runoff (which includes rivers+icebergs) and iceshelf
	1599	!! are provided but not included in emp here. Only runoff will
	1600	!! be included in emp in other parts of NEMO code
