Instructures for setting up Wave Ensemble Reforecast

  • Note this is a work in progress and the repo will be moved to a NOAA-EMC location

#Clone repo git clone https://github.com/JessicaMeixner-NOAA/wave_ens_reforecast

Checkout Model

From sorc/ directory:
sh checkout.sh

Build Model & Other Execs

From sorc/directory: sh build_ww3prepost.sh

Requests of features from Ricardo:

  • One cycle per day (starting at 03Z), with restart file for +24h
  • 5(or 11) ensemble members
  • New list of point output (parm/wave/bstations_GEFSv12WW3grid.txt)
  • New list of output fields -- Grib: HS FP DP -- Netcdf: WND HS FP T01 T02 DIR DP SPR PHS PTP PDIR
  • DT point output is 1 hour
  • DT for gridded output is 3 hours
  • We can keep grib2 format for output fields, but netcdf format for the point output files will be much easier to handle and to compare with observations;
  • Suggestion: 7 simulations (1week) per job, to optimize Orion queue time.
  • 4 streams: blocks of 5 years, starting at 2000, 2005, 2010, and 2015.

Jesssica's notes:

GEFS winds and ice: /work/noaa/marine/ricardo.campos/data/GEFSv12 Point output list: /work/noaa/marine/ricardo.campos/data/buoys/bstations_GEFSv12WW3grid.txt

  • Create mod_def once and store it
  • Prep of wind and ice will be in workflow
  • 1 forecast will use 10 nodes, 40 tasks/node takes ~32 min for 16 days or ~1 hour 7 min for 35 days
  • Restart dt will be 24 hours
  • Requested to not use check-point output and instead use one file for point/gridded output
  • Point output should be netcdf spec and table (Example templates in parm/wave dir)
  • Gridded, wants both netcdf and grib with different lists of files
  • Can clean-up binary run data as we go
  • Python post processing, Ricardo will provide script, module and resources

Issue: Need to get hpc-stack netcdf issue resolved
