1028	!! to know if the field was really received or not
1029	!!
1030	!! --> If ocean stress was really received:
1031	!!
1032	!! - transform the received ocean stress vector from the received
1033	!! referential and grid into an atmosphere-ocean stress in
1034	!! the (i,j) ocean referencial and at the ocean velocity point.
1035	!! The received stress are :
1036	!! - defined by 3 components (if cartesian coordinate)
1037	!! or by 2 components (if spherical)
1038	!! - oriented along geographical coordinate (if eastward-northward)
1039	!! or along the local grid coordinate (if local grid)
1040	!! - given at U- and V-point, resp. if received on 2 grids
1041	!! or at T-point if received on 1 grid
1042	!! Therefore and if necessary, they are successively
1043	!! processed in order to obtain them
1044	!! first as 2 components on the sphere
1045	!! second as 2 components oriented along the local grid
1046	!! third as 2 components on the U,V grid
1047	!!
1048	!! -->
1049	!!
1050	!! - In 'ocean only' case, non solar and solar ocean heat fluxes
1051	!! and total ocean freshwater fluxes
1052	!!
1053	!! ** Method : receive all fields from the atmosphere and transform
1054	!! them into ocean surface boundary condition fields
1055	!!
1056	!! ** Action : update utau, vtau ocean stress at U,V grid
