Global Forecast System (GFS) (GFS)
The United States National Centers for Environmental Prediction’s operational global numerical weather prediction system.
GFS assimilates observations and forecasts atmospheric conditions worldwide, supplying fields used in public products, GRIB services and as input to other forecast systems. Its configuration, resolution and forecast schedule are updated over time.
A single deterministic run is one possible forecast, not a certainty. Run age, valid time, grid resolution, model bias, ensemble guidance and official marine forecasts should all be considered.
