Time Coverage


  • summary: Single time dimension: for each forecast time, use GRIB record with smallest offset from reference time
  • rights: Freely available
  • processing_level: Transmitted through Unidata Internet Data Distribution.
  • processing_level: Read by CDM Grib Collection.
  • summary: NCEP Global Forecast System Model, previously called AVN/MRF (Medium Range Forecast)
  • summary: NCEP GFS Model : AWIPS 230 (G) Grid. Global Lat/Lon grid. Model runs at 0, 6, 12, and 18Z. Horizontal= 721 by 14400 points, resolution 0.25 degree, Lat/Lon projection. Vertical= 1000 to 100 hPa mandatory pressure levels (26 levels); surface, height above ground, pressure layers.
  • summary: Forecasts grids starting from the 0 hour forecast every 3 hours out to 10 days, then 12 hour forecasts for days 10-16.
