Title: The USGODAE Monterey Data Server 13 March 2007

The USGODAE Monterey Data Server13 March 2007
http// Phil Sharfstein GODAE
Project Manager
The Global Ocean Data Assimilation Experiment
  • Make ocean monitoring and prediction a routine
    activity in a manner similar to weather
  • GODAE will contribute to an information system
    for the global ocean that will serve interests
    from climate and climate change to ship routing
    and fisheries.
  • The USGODAE Server is developed and operated as a
    prototypical node for this global information

The International GODAE Project Time Line
  • 1998-1999 Concept
  • USGODAE Server begins initial development and
  • 2000-2002 Development
  • Server brought on-line as a 24x7 operational
  • Funding provided by ONR for the duration of GODAE
  • 2003-2006 Operational Demonstration
  • USGODAE Server sees steady growth in usage
  • Increased involvement in International GODAE
  • Increased breadth of data holdings
  • 2007-2008 Consolidation and Transition
  • ONR funding ends 2008
  • Server Decommissioned (If no additional funding
    is provided)
  • Goal Seek alternative funding source to ensure
    that the system remains available to support both
    DoD operations and research, and the current
    broad range of RD users.

USGODAE Server Schedule
  • 2006-2007 Full Support
  • ONR has committed to fund server operation
    through the end of the GODAE Project.
  • FNMOC will continue to provide full support for
    all server operations and data management tasks.
  • 2008 Server Decommissioned (If no additional
    funding is provided)
  • Transition Argo GDAC to other funded resource (if
  • Provide PKI data access for all DoD researchers
    currently using USGODAE.
  • Provide data distribution for FNMOC data sets
    only served by USGODAE that are used for DoD
    research (Computational Grid NOGAPS, Ocean QC,
    High-Resolution Computational Grid Ocean
    Model/Analysis Products).

    model and observational data for a broad range of
    research projects and institutions.
  • Many funded research projects that will continue
    beyond the GODAE transition period rely on
    USGODAE as their principal data source.
  • The Server provides a framework and data archive
    for DoD RD that will need to be replicated at
    each new (or existing) project.

Server User Community IOOSThe bridge between
  • The USGODAE Server currently provides a wide
    range of real-time data, and oceanic/atmospheric
    models that are essential to the success of
    several IOOS projects.
  • The Server is one of the primary real-time data
    servers for global in-situ oceanographic data.
  • The USGODAE Server is designed and operated to
    adhere to the data serving standards specified by
    the IOOS/DMAC.
  • As a partner in IOOS, FNMOC can make many of its
    higher-resolution operational model fields
    covering the waters surrounding CONUS available
    to the IOOS community.

  • Thanks to 8 years of funding from ONR, the
    USGODAE Monterey Data Server has been developed
    into an invaluable resource for both the RD
    community and the Navy operational community.
  • As planned from the outset, ONR funding for the
    Server will end at the beginning of FY08.
  • To ensure continued USGODAE Server availability
    we must enhance its role as an RD system,
    supported under the projects that have made the
    Server a key part of their data serving
  • If no additional funding is provided, the USGODAE
    Server will be decommissioned in 2008.
