# NAME

#
# refdataget.sh - get all reference data
#
# SYNOPSIS
# ========
#
# ``refdataget.sh``
#
# DESCRIPTION
# ===========
#
# Put in ${IRCAAM_ID} all the reference data files 
#
# This includes :
#
# - ARPEGE data 
#   4 parameters (rlut_d zg_d pr_d) in 5 simulations experiences
#   (CtIV CtCl AfNQIVIV AsNQIVIV TrNQIVIV) between 1971 and 2000.
#
#   You will need password from authorized people to access to ARPEGE 
#   simulation files.
#
# - OLR observation between 1974 and now.
#
# If one of these files already exists (same name), it won't be download again
# to avoid big transfert.
#
# It might be usefull to check revision of original data ...
#
#
# EXAMPLES
# ========
#
# If you are working on LOCEAN machine and you don't have any reference data, 
# you just have to run this tool :
# ::
#
# $ refdataget.sh
# 
#
# And look at log file wtih :
# ::
#
# $ tlogd.sh refdataget
# 
# and of course on files in ${IRCAAM_ID}.
#
