# ---- Ice-Sheet and Sea-Level System Model (ISSM) initialization (for LANDICE tiles)
#
# The first two parameters are arguments needed to initialize ISSM:
#
# *ISSM_EXPDIR points to the directory containing the ISSM input file, which will be
# replaced by a restart directory in the future
#
# *ISSM_EXPNAME is the name of the binary input file (ISSM_EXPNAME.bin) and PETSc
# options file (ISSM_EXPNAME.toolkits)
#
# Because we can't yet output variables defined on ISSM's mesh via HISTORY
# (e.g., via a mesh tilespace), we also have a temporary fix that will be
# eventually removed (note that output on the attached grid or landice tiles
# does still work as expected):
#
ISSM_EXPDIR: /discover/nobackup/agstubbl/GEOS/Experiments/LDAS-ISSM-dailytest/issm
ISSM_EXPNAME: GreenlandGEOS
