Ocean Model Current Areas

The NCEP Global Real-Time Ocean Forecast System (RTOFS-Global) data is based on the U.S. Navy implementation of Global HYCOM. Regional NCOM data is provided by the Naval Oceanographic Office (NAVO).

RTOFS GLOBAL MODEL INFORMATION

The Global Real-Time Ocean Forecast System is based on NAVO's configuration of the 1/12 deg. eddy resolving global HYCOM model and is initialized daily with NAVO generated initial conditions using the NCODA system. RTOFS Global is forced with NCEP's operational GFS winds. For more details see:NOAA/NCEP/MMAB RTOFS Global Web Page

REGIONAL NCOM MODEL INFORMATION

The Regional NCOM models have a resolution of 1/36 deg. (3 km). The U.S. Navy Operational Global Ocean Model (NCOM), developed by the Naval Research Laboratory (Barron et al, 1&2) and maintained by the Naval Oceanographic Office, provides boundary conditions for the regional models. The regional NCOM models found here include the U.S. East Coast (ncom_useast), The Southern California Coast (ncom_socal), Hawaii Coasts (ncom_relo_hawaii) and the Gulf of Mexico and Caribaean Seas (ncom_relo_amseas). The Navy Coupled Ocean Data Assimilation System (NCODA) provides the data assimilation for NCOM including SSH, SST, and in situ observations. For more information about NCOM see:
