|---|
| 18 | ! subroutine oasis_start_grids_writing(iwrite) |
|---|
| 19 | ! This subroutine initializes grid writing by receiving a |
|---|
| 20 | ! starting command from OASIS. |
|---|
| 21 | ! |
|---|
| 22 | ! subroutine oasis_write_grid(cgrid, nx, ny, lon, lat) |
|---|
| 23 | ! This subroutine writes longitudes and latitudes for a model |
|---|
| 24 | ! grid. |
|---|
| 25 | ! |
|---|
| 26 | ! subroutine oasis_write_corner(cgrid, nx, ny, nc, clon, clat) |
|---|
| 27 | ! This subroutine writes the longitudes and latitudes of the |
|---|
| 28 | ! grid cell corners. |
|---|
| 29 | ! |
|---|
| 30 | ! subroutine oasis_write_mask(cgrid, nx, ny, mask) |
|---|
| 31 | ! This subroutine writes the mask for a model grid |
|---|
| 32 | ! |
|---|
| 33 | ! subroutine oasis_write_area(cgrid, nx, ny, area) |
|---|
| 34 | ! This subroutine writes the grid cell areas for a model grid. |
|---|
| 35 | ! |
|---|
| 36 | ! subroutine oasis_terminate_grids_writing() |
|---|
| 37 | ! This subroutine terminates grid writing by sending a flag |
|---|
| 38 | ! to OASIS, stating the all needed grid information was written. |
