  • 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.
  • Regional NCOM is a high-resolution version of NCOM for specific areas. NCEI serves the Americas Seas, U.S. East, and Alaska regions of NCOM.
  • Global HYCOM is the Navy implementation of the Hybrid Coordinate Ocean Model (HYCOM). It is the successor to Global NCOM. This site hosts regions covering U.S. coastal waters as well as global surface fields.
  • NOAA's Real Time Ocean Forecast system (RTOFS) - Atlantic is a data-assimilating nowcast-forecast system operated by the National Weather Service National Centers for Environmental Prediction (NCEP). The model runs daily, producing a forecast out to 120 hours.
