#  This script will tar up the data for a given forecast cycle for the
#  directory specified by the first
#  argument ($1) and place the tar file on the HPSS server
#  under ${HPSSOUT}.  The tar file is put in the directory
#  appropriate for data valid for the day specified as the second 
#  command line argument ($2).
#
#  This script breaks up the fnmoc ensemble directory into four separate
#  tar files
#  
#  pgrba: all files stored in the pgrba subdirectory
#  pgrba_an: all files stored in the pgrba_an subdirectory
#  pgrba_bc: all files stored in the pgrba_bc subdirectory
#  pgrba_wt: all files stored in the pgrba_wt subdirectory
#
#  Usage: rhist_savefnmocens.sh Directory Date(YYYYMMDDHH format)
#
#  Where: Directory  = Directory to be tarred.
#         Date(YYYYMMDDHH format) = Day that the tar file should be saved under.
#
#  02/22/2007 - J. Cooke - Removed all error checking for 
#                          missing CMCENS data since it is
#                          often incomplete
#
#  11/30/2007 - J. Cooke - Added logic to being archiving track data
#
#  02/23/2011 - J. Zhu -  Modified based on cmcens script to add archive for fnmoc data
