| 4 | ! Purpose: Initial states and boundary conditions files creation: |
|---|
| 5 | ! * start.nc for dynamics (using etat0dyn routine) |
|---|
| 6 | ! * startphy.nc for physics (using etat0phys routine) |
|---|
| 7 | ! * limit.nc for forced runs (using limit_netcdf routine) |
|---|
| 8 | !------------------------------------------------------------------------------- |
|---|
| 9 | ! Notes: |
|---|
| 10 | ! * extrap=.T. (default) for data extrapolation, like for the SSTs when file |
|---|
| 11 | ! does contain ocean points only. |
|---|
| 12 | ! * "masque" can be: |
|---|
| 13 | ! - read from file "o2a.nc" (for coupled runs). |
|---|
| 14 | ! - created in etat0phys or etat0dyn (for forced runs). |
|---|
| 15 | ! It is then passed to limit_netcdf to ensure consistancy. |
