Fleet Numerical Meteorology and Oceanography Center (FNMOC) Navy Operational Global Atmospheric Prediction System (NOGAPS)

The Navy Operational Global Atmospheric Prediction System (NOGAPS) provides numerical guidance and products in support of a wide range of Navy oceanographic and atmospheric requirements. The forecast model component of NOGAPS is the heart of the system and represents a multiyear development effort by the scientists of the Naval Oceanographic and Atmospheric Research Laboratory's Atmospheric Directorate. Six-hourly data are available in GRIB1 format on regularly-spaced latitude-longitude grids at 1-degree and one-half-degree resolutions. Vertical resolution varies from 18 to 28 pressure levels, 34 sea level depths, the surface, and other various levels. Both atmospheric and ocean model variables are available.
