# The original script "create_ECDYN.sh" written by Lionel GUEZ for ERAI

# https://lmdz.lmd.jussieu.fr/utilisateurs/utilisation-de-lmdz
#
# The actual script by Ionela MUSAT is merging the ERA* data
# extracted by the get_ERA.sh script into the 
# ECDYN_${year}${month}${day}_${hour}.nc file.
#
# This script has to be called following the execution of get_ERA.sh
