| 5 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 6 | 1) Files needed from root (parent) grid |
|---|
| 7 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 8 | - coordinates.nc |
|---|
| 9 | - bathy_meter.nc |
|---|
| 10 | - bathymetry database (For example GEBCO 2014 dataset) |
|---|
| 11 | |
|---|
| 12 | |
|---|
| 13 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 14 | 2) Compile the tool |
|---|
| 15 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 16 | |
|---|
| 17 | $NEMOPATH/NEMOGCM/TOOLS/maketools -n NESTING -m X64_ADA -j 4 |
|---|
| 18 | |
|---|
| 19 | It creates 5 executables: |
|---|
| 20 | - agrif_create_coordinates.exe |
|---|
| 21 | - agrif_create_bathy.exe |
|---|
| 22 | - agrif_create_restart.exe |
|---|
| 23 | - agrif_create_restart_trc.exe |
|---|
| 24 | - agrif_create_data.exe |
|---|
| 25 | |
|---|
| 26 | |
|---|
| 27 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 28 | 3) Create coordinates and bathymetries |
|---|
| 29 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 30 | |
|---|
| 31 | a) agrif_create_coordinates.exe namelist_nordic1 |
|---|
| 32 | It creates level 1 child grid coordinates: 1_coordinates.nc |
|---|
| 33 | |
|---|
| 34 | b) agrif_create_bathy.exe namelist_nordic1 |
|---|
| 35 | It creates level 1 child grid bathymetry: 1_bathymeter.nc |
|---|
| 36 | It updates parent grid bathymetry: bathy_updated.nc |
|---|
| 37 | |
|---|
| 38 | c) agrif_create_coordinates.exe namelist_nordic2 |
|---|
| 39 | It creates level 2 child grid coordinates: 2_coordinates.nc |
|---|
| 40 | |
|---|
| 41 | d) agrif_create_bathy.exe namelist_nordic2 |
|---|
| 42 | It creates level 2 child grid bathymetry: 2_bathymeter.nc |
|---|
| 43 | It updates level 1 child grid bathymetry: 1_bathy_updated.nc |
|---|
| 44 | |
|---|
| 45 | e) agrif_create_bathy.exe namelist_nordic1_update |
|---|
| 46 | It updates parent grid bathymetry: bathy_updated_parent.nc |
|---|
| 47 | |
|---|
| 48 | Note: This last step takes into account both levels 1 and 2 bathymetries to update the parent grid bathymetry |
|---|
| 49 | to make sure that volumes match between child grids and parent grid. |
|---|
| 50 | To only perform an update as in step e), i.e. without interpolation, one has to set in the namelist: |
|---|
| 51 | - elevation_database = 1_bathy_updated.nc |
|---|
| 52 | - type_bathy_interp = 2 |
|---|
| 53 | |
|---|
| 54 | ** Files needed for your model to run: |
|---|
| 55 | - bathy_updated_parent.nc + coordinates.nc |
|---|
| 56 | - 1_bathy_updated.nc + 1_coordinates.nc |
|---|
| 57 | - 2_bathy_meter.nc + 2_coordinates.nc |
|---|
| 58 | |

|---|
| 61 | 4) Create data |
|---|
| 62 | ::::::::::::::::::::::::::::::::::::::::::::::::: |
|---|
| 63 | |
|---|
| 64 | a) agrif_create_data.exe namelist_nordic1 |
|---|
| 65 | It creates level 1 child grid data: 1_chlorophyll.nc etc |
|---|
| 66 | |
|---|
| 67 | b) agrif_create_data.exe namelist_nordic2 |
|---|
| 68 | It creates level 2 child grid data: 2_chlorophyll.nc etc |
|---|
| 69 | |
|---|
| 70 | |
