#
# Put in ${TROPFLUX_ID} OAFLUX reference file
#
# Once this tool executed :ref:`oaflux_mask_30N30S.pro` can be launched.

#
# EXAMPLES
# ========
#
# If you are working on LOCEAN machine and you don't have any reference data,
# you just have to run this tool ::
#
#  $ get_oaflux.sh
#
# And look at log file with ::
#
#  $ tlogd.sh get_oaflux
#
# and of course on files in ${TROPFLUX_ID}.
