Before submitting data to the MOTIF database, you should should follow the steps outlined in the Experimental Design section:
Please note that UNLIKE IPCC we request that THE DATA
FILES HAVE UNIQUE NAMES across the WHOLE database, and
use the following data file name template:
varname_table_experiment_modelorlab[_time-range].nc
table being one of the PMIP2
CMOR tables short names: A_FX, A_SE, A_MO, A_DA, O_SE, O_AN,
O_MO, S_SE, S_AN, S_MO, I_SE, I_DA, I_MO
experiment being one of: pmip2_0k_oa,
pmip2_0k_oav, pmip2_6k_oa, pmip2_6k_oav,
pmip2_21k_oa, pmip2_21k_oav
modelorlab should be composed of uppercase and/or lowercase
characters, numbers and/or the '-' (dash) and/or '.'
(dot) characters.
If a data file has to be split into several sub-files along the time
axis, use either
_yyyy-YYYY
if the file covers the whole years yyyy to YYYY,
or
_yyyymmdd-YYYYMMDD
There is no convention for year dates to use for the paleo
experiments, so you might as well start all the paleo experiments
on January 1st 0001 (i.e. 0001 or
00010101 and the units of the time axis should be 'days
since 0001-01-01').
You are of course free to follow whatever dating scheme you want in
your actual runs, but unified dates in the database may make some
comparison/processing steps a bit easier...
There is some logic in the file naming scheme that may be useful
for programmers! The major fields of a file name are separated by
'_' characters, which makes it easy to extract the different
fields of a file name by just splitting it where there are
'_' characters...
shell scripts users:
> fname="ts_A_MO_pmip2_0k_oa_HadCM3-MOSES2_0000-0029" > echo $fname | sed 's/_/ /g' ts A MO pmip2 0k oa HadCM3-MOSES2 0000-0029 > model=`echo $fname | cut -d_ -f7` > echo $model HadCM3-MOSES2python scripts users:
>>> fname = "ts_A_MO_pmip2_0k_oa_HadCM3-MOSES2_0000-0029" >>> ffields = fname.split('_') >>> ffields ['ts', 'A', 'MO', 'pmip2', '0k', 'oa', 'HadCM3-MOSES2', '0000-0029'] >>> model = ffields[6] >>> model 'HadCM3-MOSES2'
Try to use correct file names (even if the database file insertion
script can handle most common error and will correct the file names on
the fly)!
Also, make sure that your data files generating codes/scripts that can
handle a new naming scheme, if we have to make some changes (minor
changes, hopefully)...
Based on the data that has already been submitted to the database, you
should pay attention to the following details:
The data files will have to be sent to LSCE by anonymous ftp and/or scp
(if you already have an account at LSCE).
Data transfer by tape should only be used as a last resort (if
transfer over the network appears to be extremely slow), after
agreeing with the database administrator on what tape format should
be used.
Remember that we are not requesting as many vertical levels for the
MOTIF project as for IPCC, so the amount of data
to transfer is (much) smaller.
The data files should be stored in the following directory
hierarchy
modelorlab/yyyymmdd/experiment/table
where
yyyymmdd is the submission date
and sent either as is (the hierarchy is replicated directly
in the directory where the data is uploaded) or in a compressed tar
file with the name
modelorlab_yyyymmdd_experiment_table.tar.gz
where
yyyymmddA is the submission date followed by a
letter (a to z) if several tar files are
sent
whichever is more convenient.
Whatever transfer method is used, always keep an exact copy of the data you send, in case it needs to be sent again or reprocessed from scratch (we are not expecting a major database crash, but it is always best to be prepared... :).
And it is of course a good idea to keep all the programs/scripts you used to prepare your data in case your files need to be processed again (either because somebody find some errors in your files, or because the output standards need to be changed).
You should carefully follow those steps when you use this submission method:
