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.

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

945	!! ** Method : - Receive all the atmospheric fields (stored in frcv array). called at each time step.
946	!! OASIS controls if there is something do receive or not. nrcvinfo contains the info
947	!! to know if the field was really received or not
948	!!
949	!! --> If ocean stress was really received:
950	!!
951	!! - transform the received ocean stress vector from the received
952	!! referential and grid into an atmosphere-ocean stress in
953	!! the (i,j) ocean referencial and at the ocean velocity point.
954	!! The received stress are :
955	!! - defined by 3 components (if cartesian coordinate)
956	!! or by 2 components (if spherical)
957	!! - oriented along geographical coordinate (if eastward-northward)
958	!! or along the local grid coordinate (if local grid)
959	!! - given at U- and V-point, resp. if received on 2 grids
960	!! or at T-point if received on 1 grid
961	!! Therefore and if necessary, they are successively
962	!! processed in order to obtain them
963	!! first as 2 components on the sphere
964	!! second as 2 components oriented along the local grid
965	!! third as 2 components on the U,V grid
966	!!

968	!!
969	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
970	!! and total ocean freshwater fluxes

1360	!! 'I'-grid : B-grid lower-left corner: both components given at I-point
1361	!!
1362	!! The received stress are :

1365	!! - oriented along geographical coordinate (if eastward-northward)
1366	!! or along the local grid coordinate (if local grid)
1367	!! - given at U- and V-point, resp. if received on 2 grids
1368	!! or at a same point (T or I) if received on 1 grid
1369	!! Therefore and if necessary, they are successively
1370	!! processed in order to obtain them
1371	!! first as 2 components on the sphere
1372	!! second as 2 components oriented along the local grid

1566	!! ** Method : transform the fields received from the atmosphere into

1569	!! * total non solar, solar and freshwater fluxes (qns_tot,
1570	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
1571	!! NB: emp_tot include runoffs and calving.
1572	!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
1573	!! emp_ice = sublimation - solid precipitation as liquid
1574	!! precipitation are re-routed directly to the ocean and
1575	!! calving directly enter the ocean (runoffs are read but included in trasbc.F90)
1576	!! * solid precipitation (sprecip), used to add to qns_tot
1577	!! the heat lost associated to melting solid precipitation
1578	!! over the ocean fraction.
1579	!! * heat content of rain, snow and evap can also be provided,
1580	!! otherwise heat flux associated with these mass flux are
1581	!! guessed (qemp_oce, qemp_ice)
1582	!!
1583	!! - the fluxes have been separated from the stress as
1584	!! (a) they are updated at each ice time step compare to
1585	!! an update at each coupled time step for the stress, and
1586	!! (b) the conservative computation of the fluxes over the
1587	!! sea-ice area requires the knowledge of the ice fraction
1588	!! after the ice advection and before the ice thermodynamics,
1589	!! so that the stress is updated before the ice dynamics
1590	!! while the fluxes are updated after it.
1591	!!

1593	!! qns_tot = pfrld * qns_oce + ( 1 - pfrld ) * qns_ice => provided

1599	!! runoff (which includes rivers+icebergs) and iceshelf

1601	!! be included in emp in other parts of NEMO code
1602	!! ** Action : update at each nf_ice time step:
1603	!! qns_tot, qsr_tot non-solar and solar total heat fluxes
1604	!! qns_ice, qsr_ice non-solar and solar heat fluxes over the ice
1605	!! emp_tot total evaporation - precipitation(liquid and solid) (-calving)
