Branch / tenant: dev/gfs.v17 (gw_v17) Path: ecf/scripts/gfs/product/wave/gridded/jgfs_wave_post_gridded_master.ecf Note: Renamed from jgfs_wave_postsbs_master.ecf in v17. The Rocoto breadcrumb still references wavepostsbs.sh. Analysis date: 2026-06-11 Method: AWS Bedrock AgentCore agentcore-mcp-rag MCP cross-checked against the on-disk v17 worktree.

jgfs_wave_postsbs_master.ecf (renamed to jgfs_wave_post_gridded_master.ecf in v17) is the NCO production ecFlow task template that performs wave model post-processing — converting WaveWatch III native output into standard gridded GRIB2 products for each forecast hour. It is a _master template deployed per forecast hour. At runtime it calls JGLOBAL_WAVE_POST_GRIDDED, which drives exglobal_wave_post_gridded.sh.

Single .ecf backs per-forecast-hour tasks (jgfs_wave_post_gridded_f000.ecf, jgfs_wave_post_gridded_f003.ecf, etc.).

Converts WW3 native binary output from the forecast into standard gridded GRIB2 files:

The J-Job iterates over wavepostGRD and waveinterpGRD grid lists, creating per-grid output directories and processing each grid via the ex-script.

Uses the EE2-correct pattern: && true + err_exit.

The J-Job sources jjob_header.sh -e "wavepostgridded" -c "base wave wavepostgridded", loading:

• config.base — fundamental paths.
• config.wave — wave model settings.
• config.wavepostgridded — post grid lists and settings.

• Renamed: postsbs -> post_gridded in v17 (the Rocoto breadcrumb retains the old wavepostsbs.sh name).
• UFS modules: loads ufswm (not just run) because WW3 post tools link against the model libraries.
• Shared J-Job: supports GFS, GDAS, and EnKF members via ENSMEM conditional.
• Dynamic grid processing: uses wave_domain_grid.sh for grid resolution.
• Heavy resources: 128 cpus, 20 GB for WW3 output processing.
• _master template with per-hour deployment.
• Centralized module loading via load_modules.sh ufswm.

Note: although the graph shows 0 dependents, the wave gridded output feeds into JGLOBAL_WAVE_GEMPAK and JGLOBAL_WAVE_PRDGEN_GRIDDED (AWIPS) downstream.
