Ocean Model SST Areas

***Attention*** The NCOM regional files format was changed on April 5, 2013 by the Navy for their better use along with the new HYCOM model. The resolution was decreased slightly from 3 km to about 3.6 km but the grid regions are very close to the old files. For details please see http://ftp.opc.ncep.noaa.gov/grids/operational/NCOM/regional/LATESTNEWS.TXT

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).

***Attention*** NCOM Regional files are not available via the NCEP Nomads Open DAP server until late in the week of April 15 -19. In the mean time please use the NCDDC Ocean Nomads server for archived NCOM Data (2nd link below).

For Regional NCOM Data via ftp: ftp://http.opc.ncep.noaa.gov/grids/operational/NCOM/regional/

For archived NCOM Data: http://www.ncddc.noaa.gov/ocean-nomads/global-ncom/

For Data via Nomads GDS server: http://nomads.ncep.noaa.gov:9090/dods/ncom

For East Coast images: http://ftp.opc.ncep.noaa.gov/grids/operational/NCOM/images/

For Global RTOFS Data via ftp: http://ftp.opc.ncep.noaa.gov/grids/operational/GLOBALHYCOM/

***Attention*** NAVO's Global NCOM model has been replaced by a 1/12 deg. eddy resolving global HYCOM model on February 27, 2013. The global NCOM model data service will be terminated on March 6, 2013. NCOM data users are advised to switch to the NCEP implementation of the NAVO's global HYCOM, known as RTOFS-Global (Global Real-Time Ocean Forecast System) via the NCEP operational NOMADS server at:

http://nomads.ncep.noaa.gov:9090/

G-RTOFS 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. G-RTOFS is forced with NCEP's operational GFS winds. For more details see:NOAA/NCEP/MMAB GRTOFS 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:
