Real Time Ocean Forecast System (RTOFS)

• Four major efforts:– Eddy resolving ocean modeling.– Eddy resolving ocean initialization.

– Coupled modeling for hurricanes.

– Coupled modeling for weather – CFS / NEMS.

– All RTOFS models based on the community HYCOM model, MMAB is part of the HYCOM consortium.

RTOFS-Global– Push to global model (vs. regional models):

• Satisfy requirements from NOAA SAB (2004).• Provide BC for regional models (HWRF, NOS, IOOS).

– Adopting existing 1/12° model from NRL/NAVO (NOPP).• GFS forcing (including diurnal cycle).

– Timeline:• Operational 10/25/2011 with NRL/NAVO (NCODA) initialization (daily feed from NAVO).• FY2012: Upgrade products, analyze forcing.• FY2014/5: full initialization at NCEP. For initial capability, would like to go with NCODA as a

low-risk proven capability, and to align future research better with Navy

– NOMADS as main distribution points (OpenDAP, NetCDF).– RTOFS-Atlantic as testbed for global.– Linking to NOS Coastal Ocean Modeling Framework.– No tides yet (unlike RTOFS-Atlantic, first developed at NCEP, intend to adopt for

global from Navy)
