Outline • • Earth System Modeling Infrastructure What is Curator and ESG support to the Dycore Workshop Demonstration: – How to search for dynamical cores – How to look at models, simulations, and experiments – How to create a comparison table

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 AR 5 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
