Presentation Transcript

  1. ESMF and Curator: A comprehensive approach to model metadata Sylvia Murphy National Center for Atmospheric Research murphys@ucar.edu

  2. Outline What is Curator ESMF facilitates the collection of model metadata Metadata lifecycle Curator and ESG support to a NCAR summer 2008 colloquium on atmospheric dynamical cores Demonstration: How to search for dynamical cores How to look at models, simulations, and experiments How to create a comparison table

  3. Curator Vision: Define and implement a model metadata ontology to facilitate the search, browse, and comparison of models, components, and their datasets Portal: Built in collaboration with the Earth System Grid (ESG) enables model components, models, simulations, experiments, and data to be searched and browsed (using ESG faceted search) provides new tools to support model and component inter-comparison projects implements dataset “trackback” - connecting datasets with detailed information about the models used to create the data

  4. ESMF is facilitating metadata collection Other tools Metadata ESMF data structures and standardized interfaces XML Interoperability Database Workflow Web services Search/Browse System Configuration Tools Compare Download

  5. ESMF XML Output (example) <model_component name="Finite Volume Dynamical Core"> <discipline_set> <discipline name="Atmosphere" /> </discipline_set> <physical_domain_set> <physical_domain name=“Earth system" /> </physical_domain_set> <agency_set> <agency name="NASA" /> </agency_set> <institution_set> <institution name="Global Modeling and Assimilation Office (GMAO)" /> </institution_set> ……

  6. Metadata Lifecycle Slide from Rocky Dunlap…Georgia Institute of Technology

  7. Numerical Techniques for Global Atmospheric Models Summer Colloquium Held at NCAR during summer 2008, about 80 participants 9 atmospheric dynamical core components Running 22 test cases at up to 5 resolutions Component comparison table Automated upload of simulation data, publishing, and comparison Data search and browse via ESG Gateway

  8. Workshop Gateway http://dycore.ucar.edu/

  9. Table Comparison Interface

  10. Table Comparison Details Select model components Select criteria Table generated dynamically Eventually selections can be placed in a user’s saved workspace http://dycore.ucar.edu/query/modelComparison.htm

  11. Example Table Results

  12. Search Interface

  13. Example Trackback Page

  14. Example Component Visual

  15. Summary Together, ESMF and the Earth System Curator Project are working to develop self-describing model components whose metadata can be used by dynamic web portals to facilitate the scientific understanding of models and their datasets. www.esmf.ucar.edu www.earthsystemcurator.org
