# This script has two functions:
#  1) Generates synthetic cyclone bogus near tropical storms and appends them
#     to a PREPBUFR file (based on script variable DO_BOGUS).  If may also,
#     based on user-requested switch, flag mass pressure reports "near"
#     tropical storms.
#  2) Flag dropwinsonde wind reports "near" tropical storms (based on user-
#     requested switch).
#
#  Note: It can do both 1 and 2 above or just one of them without the other.
#   
#  (NOTE: SYNDATA is currently restricted to run with T126 gaussian
#         land-sea mask)
#
# It is normally executed by the script prepobs_makeprepbufr.sh
#  but can also be executed from a checkout parent script

# Positional parameters passed in:
#   1 - path to COPY OF input prepbufr file --> becomes output prepbufr
#       file upon successful completion of this script (note that input
#       prepbufr file is NOT saved by this script)
#   2 - path to COPY OF input tcvitals file
#   3 - expected center date in PREPBUFR file (YYYYMMDDHH)


# Imported variables that must be passed in:
#   DATA  - path to working directory
#   SGES  - path to COPY OF global simga first guess file 1 (valid at
#            either center date of PREPBUFR file or nearest cycle time prior
#            to center date of PREPBUFR file which is a multiple of 3)
#   SGESA - path to COPY OF global simga first guess file 2 (either
#            null if SGES is valid at center date of PREPBUFR file or valid
#            at nearest cycle time after center date of PREPBUFR file which
#            is a multiple of 3 if SGES is valid at nearest cycle time
#            prior to center date of PREPBUFR file which is a multiple of 3)
#   PRVT  - path to observation error table file
#   FIXSYND - path to synthethic data fixed field files
#   SYNDX   - path to SYNDAT_SYNDATA program executable
#   SYNDC   - path to SYNDAT_SYNDATA program parm cards

# Imported variables that can be passed in:
#   DO_BOGUS - Generate synthetic cyclone bogus near tropical storms and
#              append them to a PREPBUFR file (and also, based on user-
#              requested switch, flag mass pressure reports "near" tropical
#              storms)?  (choices are "YES" or "NO", anything else defaults to
#              "YES", including if this is not passed in)
#   jlogfile - string indicating path to joblog file (skipped over by this
#              script if not passed in)
#   pgmout   - string indicating path to for standard output file (skipped
#              over by this script if not passed in)
