Don't have access to the dept_system? Check out the example basis files page.
Also see the Newton pages for information about switching to newton.
You may also need to run a slightly different um setup script. ie for NEWTON:
/ohome/lrum/newton/setvars_4.5and for GREEN etc
/ohome/lrum/setvars_4.5
submodel independent | job submission, resources and re-submission patternSet run job on this host to green. Set use special command for compilation to bcompile
Now, umsubmit to wren. The job will then be passed onto green.
Alternatively look at the Green HadAM3 example job (xbepb) under the user umui on the umui.
umuiClick on Search - Filter
Enter a name for the Experiment in the requestor, and click OK.
Return to your experiment by using filter, as above, with you
username.
Altering parameters
The first parameters to change in your copied expt are the personal
details.
Click on the folder icon of your new expt to open the expt. Click on one of Jobs contained in the expt. then click File - Open Read/Write.
Click on Model Selection - User Information ... - General Details
You can find a full list of Possible output variables and their associated STASH codes here.
Change the Target Machine User-id, the Mail-id to your own.
Click Close
Choosing output variables
You'll probably want some output from your model run! This is done via the STASH Submenu. This can be somewhat confusing. Again - it's helpful to look
at an existing job, to work out what's going on here.
Create an SST Ancillary file to force the atmosphere
If you have an SST file (full values, not an anomaly file) in netCDF then you
can simply:
this will create a sst.sst file - a PP ancillary file suitable for forcing the
model.
To use this in the model open the UMUI - select you job and change Atmosphere - Ancillary and input ... - Climatologies and potent ... - Sea Surface Temperatuyre. Enter the name & location of the sst.sst file you have just created. Click on CLOSE.
Processing and Submiting the Job
Click on the PROCESS button at the bottom of the Job window.
The files will then be saved in ~/umui_jobs/ in a directory with
the relevant job name.
To submit a job you first need to create a ~/.umrc file. Copy Jeff's example file from ~jeff/.umrc.example to ~/.umrc
Change the PASSWORD to your password on the relevant machines. Change jwc to your username on the relevant machine. Then protect the file by doing
chmod 600 ~/.umrcNow, to submit a given job you need to run eg:
~jeff/bin/umsubmit xbaqawhere xbaqa is the jobname You should get a message like:
To start um job xbaqd, logon to machine turing.cfs.ac.uk and issue command: ksh $HOME/umui_runs/xbaqd-175173936/SUBMITNow follow the next section:
type groups
if you do not see 'um' then you need to get someone (eg lois) to add
you to the um group.
Ensure that you have the line
. ~lrum/newton/setvars_4.5 # set up UM 4.5 environment variablesin your .profile Now issue the command noted above
You can monitor the progress of your jobs with qstat -a
(on Green/Wren use: bjobs -a)
Continuation Runs
When you (or at least when I) set a model running, it only runs for the
first Year and then halts. This is to allow you to check everything is
running OK. Once done you can now procede with a continuation run.
TO do this:
output files live in $DUMP2HOLD/um/
restart files and pp output are directed to $DUMP2HOLD/um/
A | Daily upper air fields |
B | Daily surface and near surface fields |
C | Monthly mean upper air fields |
D | Monthly mean surface fields |
E | Monthly mean slab ocean fields |
F | Monthly mean ocean potential temperature |
G & H | Seasonal Mean Ocean Fields |
Brief summary of actual fields is: pa - daily height and temperature on four pressure levels pb - daily PMSL and surface temperature pc - monthly mean u,v, omega, height, temperature, diabatic heating on four pressure levels. Plus PV on four isentropic levels and surface pressure pd - monthly mean surface fields: lots, including surface temperature windstress and surface fluxes. pe - monthly mean slab ocean fields including temperature and ocean heat flux convergence Data volumes: One year of data requires approx: pa - 81Mb; pb - 20Mb; pc - 10Mb; pd - 15Mb; pe - 3Mb(from Rowan's pages)
Use ~lrum/bin/uminfo filename to examine file in $DUMP2HOLD/um/
use xconv to view
CRACERU* files list the outpur files. All files are UM files (not pp)? Some files are TAR'd others are not.
Did it work?
Did your run work? You probably want to read this first.
And then look at the .leave file in ~/um/umui_out
Archiving Data
You may want to read The UGAMP documantation of Automatic Archiving
Data is archived to /hold/year/lrdlrh/um_archive/
Index files: /ohome/lrum/index/
Extracting fields from the archive
I suggest using getf
