The Navy Global NCOM model is being phased out of operation, to be replaced by the higher-resolution Navy Global HYCOM. This transition is currently scheduled to take place in mid February. Some interruption of NCDDC's model data services is possible during the transition. As always, operational users are directed to the high-availability servers at the National Centers for Environmental Prediction.
Navy Coastal Ocean Model Global Domain (2008 - present)
The Global NCOM is an ocean prediction system run by the Naval Oceanographic Office (NAVOCEANO) as the Navy's real-time operational global nowcast/forecast system. The Naval Research Laboratory developed NCOM based on the Princeton Ocean Model with time invariant hybrid (sigma over Z) vertical coordinates. See Navy's NCOM Publications Web page for additional information. For distribution, NAVOCEANO interpolates the output onto a regular latitude-longitude grid in the horizontal and a series of standard depths in the vertical, and parses the global domain into 13 regions. This site provides access to regions around the U.S. and its territorial waters. Additionally, access is provided to global data for the surface only.
Users who require operational, realtime access to this data are directed to the high-availability servers at the
National Centers for Environmental Prediction.
