GFS Forecast Model
The Global Forecast System (GFS) is a weather forecast model produced by the NOAA/NWS National Centers for Environmental Prediction (NCEP). The system is a coupled model, composed of an atmosphere model, an ocean model, a land/soil model, and a sea ice model working together to produce forecasts out to 384 hours. Forecasts up to 120 hours are at a higher resolution than those after 120 hours.
