Global Real-Time Ocean Forecast System

NOTICE: As of 17 Oct 2017 at 0Z, the Global RTOFS model has been upgraded to version 1.1.2. Changes include:
  • The number of vertical layers has increased from 32 to 41.
  • The core HYCOM model has been coupled to the Los Alamos Laboratory's Community Sea Ice model (CICE)
  • Updated bathymetry
  • Updated climatology
  • Updated Equation of State from 9 to 17 terms
More information on the upgrade can be found in the Release Notes (pdf).

The global operational Real-Time Ocean Forecast System (Global RTOFS) at the National Centers for Environmental Prediction is based on an eddy resolving 1/12° global HYCOM (HYbrid Coordinates Ocean Model) and is part of a larger national backbone capability of ocean modeling at the National Weather Service in a strong partnership with the US Navy.
