Reviewed actual file modified times on NOMADS and average end times from https://www.nco.ncep.noaa.gov/pmb/nwprod/prodstat/ to set schedules as close as possible to when data is available, with a 3-minute buffer.

GEFS 35-day forecast schedule updated to wait for f384 (not f240): all 30 perturbed ensemble members' f384 files land at ~6h30m after init.

Reformat schedule changes (all times UTC, relative to init):

  • GEFS analysis: 00,06,12,18 UTC → :51 3,9,15,21 (3h51m after init; f006 ready ~3h48m)
  • GEFS forecast 35d: 07:00 daily → 06:33 daily (6h33m after 00z; f384 ready ~6h30m)

Validation schedule: set to exactly pod_active_deadline after reformat start.
