NOAA Operational Satellite Sea-surface Salinity (SSS) Data Assimilation Update
[28-Aug-2018] Bayler, E.
Presented at the 2018 Ocean Salinity Science Team and Salinity Continuity Processing Meeting
NOAA/NCEP has been running real-time operational ocean data assimilation systems since 2004. NOAA continues to pursue satellite sea-surface salinity (SSS) data for its operational models, specifically the National Weather Service's (NWS) real-time Real-Time Ocean Forecast System (RTOFS) and the real-time seasonal-interannual Global Ocean Data Assimilation System (GODAS), the ocean component of NOAA's coupled Climate Forecast System (CFS). NOAA's ocean data assimilation systems and core ocean models are both in transition. For FY19, NOAA is planning to implement the Navy Coupled Ocean Data Assimilation (NCODA) system to support initialization for RTOFS HYbrid Coordinate Ocean Model (HYCOM), with the long-term vision of evolving to implementation of the Marine Joint Effort for Data assimilation Integration (Marine-JEDI) with the Modular Ocean Model Version 6 (MOM6). On the horizon is satellite SSS data assimilation into the pending National Ocean Service's (NOS) West Coast Operational Forecast System (WCOFS), which employs the Regional Ocean Model System (ROMS). With implementation of these advanced ocean data assimilation systems, real-time ocean data monitoring and quality assurance / quality control (QA/QC) must also be developed and implemented. Consistent with developing NOAA's unified modeling framework, the ocean data assimilation QA/QC capability being pursued will address both NWS and NOS monitoring needs for both satellite and in situ data, specifically including salinity data.
