935	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,

937	!!
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
941	!!
942	!! --> If ocean stress was really received:
943	!!
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
959	!!
960	!! -->
961	!!
962	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
963	!! and total ocean freshwater fluxes
964	!!
965	!! ** Method : receive all fields from the atmosphere and transform
966	!! them into ocean surface boundary condition fields

1565	!! ** Method : transform the fields received from the atmosphere into

1568	!! * total non solar, solar and freshwater fluxes (qns_tot,
1569	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
1570	!! NB: emp_tot include runoffs and calving.
1571	!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
1572	!! emp_ice = sublimation - solid precipitation as liquid
1573	!! precipitation are re-routed directly to the ocean and
1574	!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
1575	!! * solid precipitation (sprecip), used to add to qns_tot
1576	!! the heat lost associated to melting solid precipitation
1577	!! over the ocean fraction.
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)
1581	!!
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.
1590	!!
1591	!! ** Details
1592	!! qns_tot = pfrld * qns_oce + ( 1 - pfrld ) * qns_ice => provided

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
1601	!! ** Action : update at each nf_ice time step:
1602	!! qns_tot, qsr_tot non-solar and solar total heat fluxes
1603	!! qns_ice, qsr_ice non-solar and solar heat fluxes over the ice
1604	!! emp_tot total evaporation - precipitation(liquid and solid) (-calving)
1605	!! emp_ice ice sublimation - solid precipitation over the ice
1606	!! dqns_ice d(non-solar heat flux)/d(Temperature) over the ice
