jgfs_atmos_product_master.ecf is the NCO production ecFlow task template that generates standard atmospheric GRIB2 products from GFS forecast output — the primary product generation step that creates the operational 0.25/0.50/1.00-degree pressure-level and flux GRIB2 files distributed worldwide. Per-hour _master template. Calls the shared JGLOBAL_ATMOS_PRODUCTS J-Job.

- Primary product generation: creates the 0p25/0p50/1p00 GRIB2 files that feed GEMPAK, AWIPS, NPOESS, and all downstream product chains.
- Per-hour template: one task per forecast hour, triggered after UPP master file availability.
- Exclusive host: full-node compute for wgrib2 regridding/subsetting.
- CRITICAL: upstream of all GEMPAK, AWIPS, and NPOESS product tasks.
-
Shared J-Job:
JGLOBAL_ATMOS_PRODUCTSused by both GFS and GDAS.
