How to Enable Subhourly Output in postprd/ Directory of UFS SRW App

[AyoolaAbe]

I am trying to generate subhourly output in the postprd/ directory, I want output at every 5mins using the UFS SRW Application. I’ve done some modification, but the post-processing step still only outputs files at hourly intervals.

I am working on orion, with SRW App develop version.

Compiler: intel compiler with intelmpi

I’ve checked past GitHub issues, but haven’t found guidance specific to subhourly postprd output.

Hello @AyoolaAbe.

Currently, subhourly post isn't possible in the SRW App. A PR has been opened that will add subhourly output into the SRW App, but it is low priority with respect to other work at this time.

Please look at the changes to parm/model_configure, parm/wflow/post.yaml, scripts/exregional_run_fcst.sh, scripts/exregional_run_post.sh, ush/create_model_configure_file.py, and ush/setup.py in PR #1293 to see what changes will need to be made to allow subhourly output to be generated in the SRW App.

Having done with the changes as mentioned above, how or what do i change in config.yaml to run subhourly or hourly?

Thanks.

@AyoolaAbe

In your config.yaml file, you will need to add the following:

task_run_post:
  envvars:
    SUB_HOURLY_POST: true
    DT_SUBHOURLY_POST_MNTS: 5

Here, SUB_HOURLY_POST: true will enable subhourly output and DT_SUBHOURLY_POST_MNTS: 5 will produce output every 5 minutes.

The workflow failed during JREGIONAL_RUN_FCST (task run_fcst_mem000). The immediate cause is create_model_configure_file.py erroring with missing required argument -t/--dt-atmos.
I have attached a screenshot and log file of run_fcst_mem000.

Hello @AyoolaAbe,

It looks like you removed the --dt-atmos "${DT_ATMOS}" \ line in scripts/exregional_run_fcst.sh, but didn't remove:

    parser.add_argument(
        "-t",
        "--dt-atmos",
        dest="dt_atmos",
        required=True,
        help="Forecast model's main time step.",
    )

or

        dt_atmos=str_to_type(args.dt_atmos),

from ush/create_model_configure_file.py.

Please make sure that these lines are removed, then you should be able to run the run_fcst task without this error message.
