GLOBAL FORECAST SYSTEM
Finding GDAS and GFS production run files

Select files needed to run parallels are copied to global branch disk space:
   /global/shared/dump/YYYYMMDDCC

where:

YYYY  = 4-digit year of run date
MM  = 2-digit month of run date
DD  = 2-digit day of run date
CC = run cycle (00, 06, 12 18).

These files have a different naming convention from that of NCO. A mapping of those file names is available here.

If other files are needed, eg, for verification:

NCO maintains files for the last 10 days in CCS directories:

/com/gfs/prod/gdas.YYYYMMDD
    and
/com/gfs/prod/gfs.YYYYMMDD

Locations of production files on HPSS (tape archive)

/NCEPPROD/hpssprod/runhistory/rhYYYY/YYYYMM/YYYYMMDD/
/NCEPPROD/2year/hpssprod/runhistory/rhYYYY/YYYYMM/YYYYMMDD/
/NCEPPROD/1year/hpssprod/runhistory/rhYYYY/YYYYMM/YYYYMMDD/

Examples:

/NCEPPROD/hpssprod/runhistory/rh2007/200707/20070715/
/NCEPPROD/2year/hpssprod/runhistory/rh2007/200707/20070715/
/NCEPPROD/1year/hpssprod/runhistory/rh2007/200707/20070715/

To see, eg, which files are stored in the 2-year archive of gfs model data:

d2n6 93 % /nwprod/util/ush/hpsstar dir /NCEPPROD/2year/hpssprod/runhistory/rh2007/200707/20070715 | grep gfs_prod_gfs
