GFS Model

The Global Forecasting System or GFS (formerly called the Aviation Model) contains forecast data every 3 hours from forecast hours 0 to 84 on a 1 degree latitude/longitude grid covering the globe. In addition, we map this data to northern and southern hemispheric 257 x 257 grids for use by programs other than HYSPLIT. The model data is updated 4 times per day. Northern hemisphere domain map. Southern hemisphere domain map.
