Configure your run

The global-workflow configs contain default settings that match operations. Users wishing to run with different settings should adjust their $EXPDIR configs and then rerun the setup_workflow[_fcstonly].py script since some configuration settings/switches change the workflow/xml ("Adjusts XML" column value is "YES").

Switch	What	Default	Adjusts XML	More Details
EXP_WARM_START	Is experiment starting warm (.true.) or cold (.false)?	.false.	NO	Impacts IAU settings for initial cycle. Can also be set when running setup_expy[_fcstonly].py script with --start flag (e.g. --start warm)
RETRO	Use retrospective parallel for ICs	NO	NO	Default of NO will tell getic job to pull from production tapes.
RUN_CCPP	Run CCPP	NO	NO	If YES, set desired suite for CCPP_SUITE variable. CCPP will become default soon, variable may be removed. Click for further instructions on running CCPP
QUILTING	Use I/O quilting	.true.	NO	If .true., choose OUTPUT_GRID as cubed_sphere_grid in netcdf or gaussian_grid
OUTPUT_GRID	Output grid type	gaussian_grid	NO	If gaussian_grid, set OUTPUT_FILE for nemsio or netcdf
OUTPUT_FILE	Output file type	netcdf	NO	GFSv16 uses netcdf, GFSv15 used nemsio, recommend netcdf
WRITE_DOPOST	Run inline post	.true.	NO	If .true., produces master post output in forecast job
DOIAU	Enable 4DIAU for control with 3 increments	YES	NO	New for GFSv16
DOHYBVAR	Run EnKF	YES	YES	Don't recommend turning off
DONST	Run NSST	YES	NO	If YES, turns on NSST in anal/fcst steps, and turn off rtgsst
DO_GLDAS	Run GLDAS to spin up land ICs	YES	YES	Spins up for 84hrs if sflux files not available
DO_WAVE	Runs wave jobs and produce wave forecast output	YES	YES	One-way wave coupling, new for GFSv16
DO_BUFRSND	Run job to produce BUFR sounding products	NO	YES	downstream processing
DO_GEMPAK	Run job to produce GEMPAK products	NO	YES	downstream processing, ops only
DO_AWIPS	Run jobs to produce AWIPS products	NO	YES	downstream processing, ops only
WAFSF	Run jobs to produce WAFS products	NO	YES	downstream processing, ops only
DO_VRFY	Run vrfy job	NO	YES	Whether to include vrfy job (GSI monitoring, tracker, VSDB, fit2obs)
DO_METP	Run METplus jobs	YES	YES	One cycle spinup
DO_VSDB	Run VSDB package	YES	NO	Retiring in GFSv17+
LOCALARCH	Archive to a local directory	NO	Possibly	Instead of archiving data to HPSS, archive to a local directory, specified by ATARDIR. If LOCALARCH=YES, then HPSSARCH must =NO. Changing HPSSARCH from YES to NO will adjust the XML.
