Do you wish to run the COUPLED Ocean/Sea-Ice Model? (Default: NO or FALSE)

The default will run the atmospheric model with the ocean as a boundary condition.

Enter the Data_Ocean Horizontal Resolution code: o1 (1 -deg, 360x180, (e.g. Reynolds) Default)

o8 (1/8-deg, 2880x1440, (e.g. OSTIA))

These are two different sea surface temperature products for boundary conditions.

Do you wish to run GOCART? (Default: NO or FALSE)

GOCART is the interactive chemistry component -- otherwise prescribed chemistry (PCHEM) is used.

Enter the tag or directory (/filename) of the HISTORY.AGCM.rc.tmpl to use

The <code>umask 022</code> is not strictly necessary, but it will make the various files readable to others, which will facilitate data sharing and user support. Your home directory <code>~''USERID''</code> is also inaccessible to others by default; running <code>chmod 755 ~</code> is helpful.

Copy the restart (initial condition) files and associated <code>cap_restart</code> into ''EXPDIR''. Keep the "originals" handy since if the job stumbles early in the run it might stop after having renamed them. The model expects restart filenames to end in "rst" but produces them with the date and time appended, so you may have to rename them back to ending in "rst". The <code>cap_restart</code> file is sometimes provided with a set of restarts, but if not you can create it: it is simply one line of text with the date of the restart files in the format ''<code>YYYYMMDD HHMMSS</code>'' (with a space). The boundary conditions/forcings are provided by symbolic links created by the run script. If you need an arbitrary set of restarts, you can copy them from <code>/archive/u/aeichman/restarts/Ganymed-~~1_0~~/</code>, where they are indexed by resolution and date. If you are unfamiliar with the way that the <code>/archive</code> filesystem works, keep in mind that a <code>cp</code> from there might appear to stall while the tape is loaded -- see the NCCS documentation for details.

The script you submit, <code>gcm_run.j</code>, is in ''HOMEDIR''. It should be ready to go as is. The parameter END_DATE in <code>CAP.rc</code> can be set to the date you want the run to stop. An alternative way to stop the run is by commenting out the line <code> if ( $capdate < $enddate ) qsub $HOMDIR/gcm_run.j</code> at the end of the script, which will prevent the script from being resubmitted, or rename the script file, or kill the job (described below).

The contents of the output files (including which variables get saved) may be configured in the <code>''HOMEDIR''/HISTORY.rc</code> -- a good description of this file may be found at http://modelingguru.nasa.gov/clearspace/docs/DOC-1190 .
