Atmos data for first fhr not being produced when REPLAY_ICS is set to YES #2754

Closed EricSinsky-NOAA closed 3 weeks ago

EricSinsky-NOAA commented 2 months ago

What is wrong?

When REPLAY_ICS is set to YES, the f003 atmos master data is not generated in the forecast job. This causes the f003 atmos prod jobs to stall, resulting in missing f003 atmos prod data.

What should have happened?

f003 atmos master data should be generated in the forecast job. Then the f003 atmos prod task should be triggered and produce f003 atmos prod data.

What machines are impacted?

All or N/A

Steps to reproduce

  1. Set REPLAY_ICS to YES.
  2. Include atmosphere as one of the components.

Additional information

This was tested using GEFS. FHOUT_HF_GFS was set to 3 and FHOUT_GFS was set to 6.

Do you have a proposed solution?

To resolve this issue, the first lead time to be outputted must be ${OFFSET_START_HOUR}+(${DELTIM}/3600). For example, when REPLAY_ICS is set to YES, OFFSET_START_HOURis set to 3, and DELTIMis 300, the first lead time for the atmos prod output should be approximately 3.0833. This fix was applied in the EP5r2 model runs. There is a feature branch with a fix to this issue and a PR will be submitted to global-workflow.
