Open BinLiu-NOAA opened 9 months ago
The atmosphere-only forecast restart capability has been developed and established with the upcoming HAFSv2 upgrade.
When the forecast job is requested/triggered/instructed to run, the restarted forecast can automatically pick up the latest restart forecast hour (with complete set restart files) and continue finishing the rest of the forecast hours. Currently, from EMC development side, we have tested the writing out restart files for potential restart hours at both every 12 hours and every 24 hours. Both configurations worked fine from our end.
Here some notes/information when considering at what interval we want to write out the restart files for potential restart runs. Currently, HAFS forecast job with operational computation resources can complete 12-hour forecast in ~9 min, and 24-hour forecast in ~18 min. And the size of every set of the forecast restart files is ~ 20GB.
