| 1 | This directory contains some prototypes and example of programs |
|---|
| 2 | and scripts to generate initial condition files for Venus-DYNAMICO |
|---|
| 3 | from a Venus PCM (lon-lat) start_archive file |
|---|
| 4 | |
|---|
| 5 | Preliminary steps and requirements: |
|---|
| 6 | ---------------------------------- |
|---|
| 7 | - You must have run a Venus-DYNAMICO simulation (with startphy_file=.false.) |
|---|
| 8 | at the sought horizontal (nbp=...) and vertical (llm=...) resolution |
|---|
| 9 | to have adequate start.nc and startphy.nc files |
|---|
| 10 | called start_icosa_ref.nc and startphy_icosa_ref.nc hereafter |
|---|
| 11 | - You will need at start_archive.nc file obtained from a Venus PCM run. |
|---|
| 12 | - You need a high resolution topography file, e.g. topo_Thomas_inv_nc4.nc |
|---|
| 13 | |
|---|
| 14 | - You need some NCO tools to post-process/adapt some of the NetCDF files |
|---|
| 15 | |
|---|
| 16 | In a nutshell: |
|---|
| 17 | -------------- |
|---|
| 18 | 1) The input start_archive.nc needs to be converted to NetCDF4 format |
|---|
| 19 | (for compliance with XIOS); you can use "nccopy" for that: |
|---|
| 20 | nccopy -k 4 start_archive.nc start_archive_nc4.nc |
|---|
| 21 | |
|---|
| 22 | 2) Two Fortran programs, start_archive2icosa.f90 and rearrange_startphy.f90 |
|---|
| 23 | will be needed, so you have to compile them |
|---|
| 24 | An example "compile" script is provided, which you'll need to adapt to |
|---|
| 25 | your own settings to generate executables start_archive2icosa and |
|---|
| 26 | rearrange_startphy |
|---|
| 27 | |
|---|
| 28 | 3) You should first run "start_archive2icosa". It needs quite a bit of memory |
|---|
| 29 | and cores so you'll probably need to create and submit a job |
|---|
| 30 | script "job_start_archive2icosa" is provided as an illutrative example |
|---|
| 31 | to adapt to your own system. |
|---|
| 32 | To run, "start_archive2icosa" needs: |
|---|
| 33 | start_archive_nc4.nc, start_icosa_ref.nc, startphy_icosa_ref.nc, |
|---|
| 34 | topo_Thomas_inv_nc4.nc and iodef.xml |
|---|
| 35 | You may need to adapt iodef.xml to match variable names in start_icosa_ref.nc |
|---|
| 36 | (especially if you have tracers which might have different names) |
|---|
| 37 | Upon successful completion, the program will generate two files: |
|---|
| 38 | "start_icosa.nc" and "startphy_icosa.nc" |
|---|
| 39 | |
|---|
| 40 | 4) Some further tailoring is needed, including a reordering of columns |
|---|
| 41 | (via the rearrange_startphy program) and some minor additions. |
|---|
| 42 | All this is handled by the icosa_finalize.bash script which should be run |
|---|
| 43 | and will generate start.nc and startphy.nc files usable by Venus-DYNAMICO |
|---|
| 44 | |
