Full paths for some UM inputs

[aidanheerdegen]

There appear to still be some full paths to files in the UM config. These files will not be tracked in the manifests.

atmosphere/ihist: VERT_LEV        = 'VERT_LEV: $UMDIR/vn7.3/ctldata/vert/vertlevs_G3                                 ',
atmosphere/ihist: NDEPFIL = 'NDEPFIL  : /g/data1a/p66/txz599/data/ancil/CMIP6/Ndep_1850_ESM1.anc

atmosphere/INITHIS: VERT_LEV='VERT_LEV: $UMDIR/vn7.3/ctldata/vert/vertlevs_G3',
atmosphere/INITHIS:NDEPFIL= 'NDEPFIL  : /g/data1a/p66/txz599/data/ancil/CMIP6/Ndep_1850_ESM1.anc',

atmosphere/um_env.py:'ASTART': '/scratch/p66/hxw599/packed_up/input/start_dump/pre-industrial.astart
',

These absolute paths should be moved to paths relative to the work/atmosphere directory and the paths to these files added as sources (input) in config.yaml

Maybe the input files are ok due to the way the UM find files. There are these definitions also:

atmosphere/um_env.py:'VERT_LEV': 'INPUT/vertlevs_G3',
atmosphere/um_env.py:'NDEPFIL': 'INPUT/Ndep_1850_ESM1.anc',

And it looks like they're being resolved correctly:

$ ls -l work/atmosphere/INPUT/Ndep_1850_ESM1.anc
lrwxrwxrwx 1 aph502 v45 81 May 25 14:08 work/atmosphere/INPUT/Ndep_1850_ESM1.anc -> /g/data/access/payu/access-esm/input/pre-industrial/atmosphere/Ndep_1850_ESM1.anc
$ ls -l /g/data/access/payu/access-esm/input/pre-industrial/atmosphere/vertlevs_G3
-r-xr-x---+ 1 hxw599 access 948 May 19 14:11 /g/data/access/payu/access-esm/input/pre-industrial/atmosphere/vertlevs_G3

In which case probably best to just remove those confusing paths from those other files?

That ASTART file needs to be moved to a restart location though I would have thought, and referenced locally (INPUT/.....)

It is a bit tricky to figure out exactly what payu has done because environment um_env.py is substituted at the time the model is run. Here are the UM related environment variables when run as-is

AINITIAL: ''
ARCLBIOG: INPUT/biogenic_351sm.N96L38
ASTART: restart_dump.astart
AUSCOM_CPL: 'true'
BIOMASS: INPUT/Bio_1850_ESM1.anc
CHEMOXID: INPUT/sulpc_oxidants_N96_L38
DATAW: /scratch/v45/aph502/access-esm/work/esm-pre-industrial-clean/atmosphere
NDEPFIL: INPUT/Ndep_1850_ESM1.anc
OCFFEMIS: INPUT/OCFF_1850_ESM1.anc
OZONE: INPUT/ozone_1850_ESM1.anc
PAREXE: parexe
PRINT_STATUS: PrStatus_Diag
RPSEED: ''

SOOTEMIS: INPUT/BC_hi_1850_ESM1.anc

VERT_LEV: INPUT/vertlevs_G3
VN: '7.3'

And the manifest/restart.yaml shows the ASTART file is correct (work is a symbolic link to /scratch/v45/aph502/access-esm/work/esm-pre-industrial-clean):

work/atmosphere/restart_dump.astart:
  fullpath: /g/data/access/payu/access-esm/restart/pre-industrial/atmosphere/restart_dump.astart   
  hashes:
    binhash: 7a09f2265594948d0ed84ecf996b7338
    md5: f31560220e51d999f9dae5820d73cca8

So it looks like it is doing the right thing, but I still think we shouldn't have absolute paths in the default um_env.py as it is confusing. Better to set it to nothing.
