The Unified Model (UM) and it's user interface (UMUI)

Ways of cleaning up after the UM (by directory):

• um_archive/job/ppfiles:

Convert the files to pp, and zip any that you think you won't need often (e.g. I regularly use the atmospheric files, so zip the ocean ones).

• um_archive/job/dumps:

Much of the contents can go, but don't delete *all* of these, as they contain fields which can be used to restart the model, e.g. to continue the run. One strategy is to delete all dumps but one for each year, to enable a restart from any year. Alan Iwi's webiste has a utility which will reduce the size of the dump by removing the fields which are not necessary to restart the model, and you can further reduce the size by gzipping them. http://home.badc.rl.ac.uk/iwi/um/utils.html#subset

• datam/job/

These can go, as long as your output is appearing in /um_archive/ppfiles and not here. Most of the files should get deleted as it goes along, but there will be some datafiles from near the end of the run, and probably some partial sum files from the climate meaning system. By deleting these files, you'll lose the ability to resume the run in the middle of a climate mean period and still get out the means for that period, but in practice that's tricky to do anyway, so it's probably not so important.

• umui_runs/job/

These can definitely go, but they shouldn't be large anyway.

• Is there anything else I should consider cleaning out after a successful run?

Not much. There will be some files in dataw you might choose to get rid
of, but the only thing of significant size is probably the reconfigured
start dump, although potentially the ascii output files could get large if
for example you have a large ensemble on many processors with additional
print statements. There's also the executable and other compilation stuff
in there, that you may or may not want to keep.

There are also some files to do with the run in your "tmp" directory,
although these aren't large, and if you're using the "tidyup" script mod
then these should already be getting deleted.
