Meteorological Forecast – Regional Surface Pressure

The operational atmospheric forecasts that make use data from the Global Forecast System (GFS). The entire globe is covered by the GFS at a base horizontal resolution of 28 km. The model is run by NCEP four times a day: 00Z, 06Z, 12Z, and 18Z.  Each run produces forecasts of every 3 hours from the initial time out to 16 days.
