The Global Forecast System (GFS) is a global numerical weather prediction model operated by the National Oceanic and Atmospheric Administration (NOAA).
Global coverage at 25km resolution (720x1440 grid)
Four daily runs (00, 06, 12, 18 UTC)
Extended prediction horizons up to 16 days
Real-time data access via Python SDK or REST API
GFS uses standardized variable naming conventions. For full details on the naming structure, see Weather Variable Naming.
