Operational Flow¶

The InaCAWO operational forecast system is a fully automated pipeline managed by ROME (Baron Real-Time Operational Modeling Environment) on the BMKG HPC. Cron-scheduled job scripts orchestrate data ingest, pre-processing, model spin-up, analysis cycling, forecast runs, and post-processing.

High-level workflow¶

    A[Global model data ingest] --> B[Pre-processing IC/BC]
    B --> C[Model spin-up]
    C --> D[6-hourly analysis cycling]
    D --> E[Forecast run]
    E --> F[Post-processing]
    F --> G[Dissemination]

Processing stages¶

Stage	Description	Frequency
Data ingest	Download ECMWF, CMEMS Mercator, GFS, GFSWAVE, HYCOM	Per cycle / daily
Pre-processing	Generate WRF, ROMS, SWAN IC/BC and forcing files	Per cycle
Spin-up	72-hour standalone ROMS and SWAN spin-up runs	1–4× daily
Analysis cycling	6-hour coupled-model spin-up (T−6 to T0)	Every 6 hours
Forecast	10-day (00/12 UTC) or 90-hour (06/18 UTC) coupled run	4× daily
Post-processing	NetCDF reformatting, plotting, FTP delivery	Concurrent with forecast

Forecast cycles¶

Cycle (UTC)	Forecast length	Atmospheric IC/BC	Output products
00, 12	10 days (240 h)	ECMWF (primary), GFS (backup)	FULL + ESSENTIAL
06, 18	90 hours	GFS only	FULL only
