Ocean Model Current Areas
The NCEP Global Real-Time Ocean Forecast System (Global RTOFS) 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.
Global RTOFS is forced with NCEP's operational GFS winds.
For more details see:NOAA/NCEP/MMAB Global RTOFS 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:
