|---|
| 26 | !! ** Purpose : provide to the ocean the stress at each time step |
|---|
| 27 | !! |
|---|
| 28 | !! ** Method : Read the daily surface stress components in NetCDF |
|---|
| 29 | !! file. They are given in the (i,j) referential |
|---|
| 30 | !! The i-component is given at U-point (INTERP package) |
|---|
| 31 | !! The j-component is given at V-point (INTERP package) |
|---|
| 32 | !! |
|---|
| 33 | !! CAUTION: never mask the surface stress field ! |
|---|
| 34 | !! |
|---|
| 35 | !! ** Action : update at each time-step the two components of the |
|---|
| 36 | !! surface stress in both (i,j) and geographical referencial |
