  1. JCSDA Ocean Working Group Jim Cummings, NRL (co-chair) Hendrik Tolman, NCEP (co-chair) Laury Miller, NESDIS Eric Bayler, NESDIS Guillaume Vernieres, GMAO Dave Behringer Michele Rienecker Expect to bring in FFO scientists

  2. JCSDA Oceans WG Objectives • Coordinate efforts on the processing of altimeter data to improve the consistency between different data sources, and the estimates of tides, the geoid and mean ocean dynamic topography. • Coordinate efforts to develop improved assimilation of altimetry data. • Construct and conduct experiments that contribute to design considerations and justification for Jason-3 and SWOT. • Coordinate efforts to develop more sophisticated and physically-based assimilation methods for mean and spectral satellite observations of surface wind waves, especially from SAR wave data. • Coordinate efforts aimed at assimilating satellite sea-surface salinity (SSS) data. • Coordinate experiments that document the impact of data types identified by the Working Group.

  3. 1st Meeting: April 23rd, 2009 • Discussion about the scope and objectives • Focus: Operational ocean data assimilation systems • Shared information about systems • Action item: Provide information about data sets ingested and the data source

  4. JCSDA Oceans & Satellite Data • Currently assimilating: • SST retrievals • sea-ice concentration • sea-surface height anomalies (from altimetry) • significant wave height (from altimetry). • Preparing for sea-surface salinity (SMOS and Aquarius) • Models: • HYCOM: NCEP (Real-time Ocean Forecast) and NRL • WW3: NCEP and NRL • MOM4: NCEP GODAS (climate) and GMAO • Assimilation Methods: • NRL: NCODA MVOI is operational at FNMOC and NAVO, and runs in R&D with HYCOM • NCEP: univariate 3Dvar with MOM4; OI, 2Dvar with HYCOM • GMAO: MvOI and EnKF with MOM4
