what is gfs
This image was produced with the Grid Analysis and Display System (GrADS) and ImageMagick. The Global Forecast System (GFS) is a weather forecast model produced by the National Centers for Environmental Prediction (NCEP).Dozens of atmospheric and land-soil variables are available through this dataset, from temperatures, winds, and precipitation to soil moisture and atmospheric ozone concentration.he GFS model is a coupled model, composed of four separate models (an atmosphere model, an ocean model, a land/soil model, and a sea ice model), which work together to provide an accurate picture of weather conditions. Changes are regularly made to the GFS model to improve its performance and forecast accuracy.
