| 478 | ==== Setup ==== |
| 479 | |
| 480 | Firstly `init_nemovar.sh` is run. |
| 481 | Links are created to the ancillary files, the coordinates and the bathymetry. |
| 482 | Additionally the `$DIR_INPUT` directory is created and the innovations, the assimilation background and the altimeter bias are linked into it. |
| 483 | |
| 484 | The namelist used is called `namelist.nemovar`. It is updated with the variable: |
| 485 | {{{ |
| 486 | nn_date0 "$(rose date -c -f %Y%m%d)" |
| 487 | }}} |
| 488 | |
| 489 | The script then calls `run_nemovar.sh`. |
| 490 | |
| 491 | |
| 492 | |
| 493 | ==== Run ==== |
| 494 | |
| 495 | |
| 496 | ==== Finalisation ==== |
| 497 | |
| 498 | If `run_nemovar.sh` completes succesfully then more steps in `init_nemovar.sh` are performed. |
| 499 | The directory `$OUTDIR_INCREMENTS` is created and the increments produced in the NEMOVAR stage are combined into one file: |
| 500 | {{{ |
| 501 | rebuild_nemo increments_o01 ${NEMO_NPROC} |
| 502 | mv increments_o01.nc ${OUTDIR_INCREMENTS}/assim_background_increments.nc |
| 503 | }}} |
| 504 | The same is also done for the altimeter bias (`altbias`). |
| 505 | |
| 506 | The file `assim_background_increments.nc` is one of the more important files; it contains the increments after each stage. |
| 507 | These increments are applied to the background to create the analysis **x,,a,,**. |
