What is Curator

• The Earth System Curator project, in partnership
  with the Earth System Grid (ESG), is building a
  web portal that links model components and data
  together via metadata.
• The portal enables components, models,
  simulations, and data to be searched, browsed,
  downloaded, and compared.
• The portal and metadata were used to support the
  ASP 2008 Colloquium
• Project is part of the larger ESMI effort.
  Cecelia Deluca is the PI, Sylvia Murphy is the
  project manager.
• The portal is planned for use in IPCC AR5 as part
  of ESG.
• Other partners include ESMF, Georgia Tech, GFDL,
  and members of the European model metadata
  community.

ASP 2008 Colloquium Numerical Techniques for
Global Atmospheric Models

• 10 modeling groups with 11 atmospheric dycore
  components
• Running 22 test cases at up to 5 resolutions
• Component comparison table
• Automated upload of simulation data, publishing,
  and comparison
• Current PCMDI tables are static, hard-coded,
  non-searchable
• Data search and browse via ESG Gateway
• Presentation on use of metadata for MIPs for
  student attendees

Table Comparison Details

• Select model components
• Select criteria
• Table generated dynamically
• Eventually selections can be placed in a users
  saved workspace
