[1218]	805	!! - transform the received ocean stress vector from the received
	806	!! referential and grid into an atmosphere-ocean stress in
	807	!! the (i,j) ocean referencial and at the ocean velocity point.
	808	!! The received stress are :
	809	!! - defined by 3 components (if cartesian coordinate)
	810	!! or by 2 components (if spherical)
	811	!! - oriented along geographical coordinate (if eastward-northward)

	813	!! - given at U- and V-point, resp. if received on 2 grids

	815	!! Therefore and if necessary, they are successively

	1327	!! ** Purpose : provide the heat and freshwater fluxes of the

	1329	!!
	1330	!! ** Method : transform the fields received from the atmosphere into
	1331	!! surface heat and fresh water boundary condition for the
	1332	!! ice-ocean system. The following fields are provided:
	1333	!! * total non solar, solar and freshwater fluxes (qns_tot,
	1334	!! qsr_tot and emp_tot) (total means weighted ice-ocean flux)
	1335	!! NB: emp_tot include runoffs and calving.
	1336	!! * fluxes over ice (qns_ice, qsr_ice, emp_ice) where
	1337	!! emp_ice = sublimation - solid precipitation as liquid
	1338	!! precipitation are re-routed directly to the ocean and
	1339	!! runoffs and calving directly enter the ocean.
	1340	!! * solid precipitation (sprecip), used to add to qns_tot
	1341	!! the heat lost associated to melting solid precipitation
	1342	!! over the ocean fraction.
	1343	!! ===>> CAUTION here this changes the net heat flux received from
	1344	!! the atmosphere
	1345	!!
	1346	!! - the fluxes have been separated from the stress as
	1347	!! (a) they are updated at each ice time step compare to
	1348	!! an update at each coupled time step for the stress, and
	1349	!! (b) the conservative computation of the fluxes over the
	1350	!! sea-ice area requires the knowledge of the ice fraction
	1351	!! after the ice advection and before the ice thermodynamics,
	1352	!! so that the stress is updated before the ice dynamics
	1353	!! while the fluxes are updated after it.
	1354	!!
	1355	!! ** Action : update at each nf_ice time step:
[3294]	1356	!! qns_tot, qsr_tot non-solar and solar total heat fluxes
