NCEP GFS 0.25 Degree Global Forecast Auxiliary Grids Historical Archive

The NCEP operational Global Forecast System auxiliary analysis and forecast grids are on a 0.25 by 0.25 global latitude longitude grid. Grids include analysis and forecast time steps at a 3 hourly interval from 0 to 240, and a 12 hourly interval from 240 to 384. Model forecast runs occur at 00, 06, 12, and 18 UTC daily. For real-time data access please use the NCEP data server.
