858	!! ** Purpose : provide the stress over the ocean and, if no sea-ice,
859	!! provide the ocean heat and freshwater fluxes.
860	!!
861	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
862	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
863	!! to know if the field was really received or not
864	!!
865	!! --> If ocean stress was really received:
866	!!
867	!! - transform the received ocean stress vector from the received
868	!! referential and grid into an atmosphere-ocean stress in
869	!! the (i,j) ocean referencial and at the ocean velocity point.
870	!! The received stress are :
871	!! - defined by 3 components (if cartesian coordinate)
872	!! or by 2 components (if spherical)
873	!! - oriented along geographical coordinate (if eastward-northward)
874	!! or along the local grid coordinate (if local grid)
875	!! - given at U- and V-point, resp. if received on 2 grids
876	!! or at T-point if received on 1 grid
877	!! Therefore and if necessary, they are successively
878	!! processed in order to obtain them
879	!! first as 2 components on the sphere
880	!! second as 2 components oriented along the local grid
881	!! third as 2 components on the U,V grid
882	!!
883	!! -->
884	!!
885	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
886	!! and total ocean freshwater fluxes
887	!!
888	!! ** Method : receive all fields from the atmosphere and transform

1208	!! and at the velocity point of the sea-ice model (cp_ice_msh):
1209	!! 'C'-grid : i- (j-) components given at U- (V-) point
1210	!! 'I'-grid : B-grid lower-left corner: both components given at I-point
1211	!!
1212	!! The received stress are :
1213	!! - defined by 3 components (if cartesian coordinate)
1214	!! or by 2 components (if spherical)
1215	!! - oriented along geographical coordinate (if eastward-northward)
1216	!! or along the local grid coordinate (if local grid)
1217	!! - given at U- and V-point, resp. if received on 2 grids
1218	!! or at a same point (T or I) if received on 1 grid
1219	!! Therefore and if necessary, they are successively
1220	!! processed in order to obtain them
1221	!! first as 2 components on the sphere
1222	!! second as 2 components oriented along the local grid

1415	!! ** Purpose : provide the heat and freshwater fluxes of the
1416	!! ocean-ice system.
1417	!!
1418	!! ** Method : transform the fields received from the atmosphere into
1419	!! surface heat and fresh water boundary condition for the
1420	!! ice-ocean system. The following fields are provided:
1421	!! * total non solar, solar and freshwater fluxes (qns_tot,
1422	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
1423	!! NB: emp_tot include runoffs and calving.
1424	!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
1425	!! emp_ice = sublimation - solid precipitation as liquid
1426	!! precipitation are re-routed directly to the ocean and
1427	!! runoffs and calving directly enter the ocean.
1428	!! * solid precipitation (sprecip), used to add to qns_tot
1429	!! the heat lost associated to melting solid precipitation
1430	!! over the ocean fraction.
1431	!! ===>> CAUTION here this changes the net heat flux received from
1432	!! the atmosphere
1433	!!
1434	!! - the fluxes have been separated from the stress as
1435	!! (a) they are updated at each ice time step compare to
1436	!! an update at each coupled time step for the stress, and
1437	!! (b) the conservative computation of the fluxes over the
1438	!! sea-ice area requires the knowledge of the ice fraction
1439	!! after the ice advection and before the ice thermodynamics,
1440	!! so that the stress is updated before the ice dynamics
1441	!! while the fluxes are updated after it.
1442	!!
1443	!! ** Action : update at each nf_ice time step:
1444	!! qns_tot, qsr_tot non-solar and solar total heat fluxes
1445	!! qns_ice, qsr_ice non-solar and solar heat fluxes over the ice
1446	!! emp_tot total evaporation - precipitation(liquid and solid) (-runoff)(-calving)
1447	!! emp_ice ice sublimation - solid precipitation over the ice
1448	!! dqns_ice d(non-solar heat flux)/d(Temperature) over the ice
