# Script name:   ingest_cloud_NASA.sh
#
# JIF contact:  J. Ator     Org: NCO         Date: 2010-06-12
#
# Abstract: This script reads a file of NASA Langley cloud pixel data,
#   converts it to NCEP BUFR format, and writes it to the observational
#   database.
#
# Script history log:
# 2010-06-12  Jeff Ator     Original version for implementation
#
# Usage: ingest_cloud_NASA.sh  $1 $2
#
#   Script parameters: $1 - full path definition for BUFR mnemonic table
#                      $2 - full path definition for NASA Langley data file
#
#   Modules and files referenced:
#     scripts     : $DATA/prep_step
#                   $DATA/postmsg
#                   $USHbufr/tranjb
#     executables : $EXECbufr/decod_dcncld
#
# Remarks:
#
#   Invoked by the script ingest_translate_orbits.
#
#   Imported variables that must be passed in:
#      DATA     - path to current working directory
#      USHbufr  - path to ush scripts
#      EXECbufr - path to executables
#      TANKDIR  - path to output BUFR database (e.g., /dcom/us007003)
#
#   Condition codes:
#     0 - no problem encountered
#   > 0 - some problem encountered
#     Specifically: 100 - input NASA Langley cloud pixel data file not found
#                   110 - unable to create BUFR output; see decoder log
#                         $TANKDIR/decoder_logs/decod_dcncld.log for details
#                   120 - unable to ingest BUFR output in database; see
#                         $TANKDIR/errlog.out for details
#
# Attributes:
#   Language: UNIX script
#   Machine:  NCEP CCS
