  1. The Earth System Grid: Turning Climate Datasets into Community Resources www.earthsystemgrid.org

  2. The growing importance of climate simulation data Results from the Parallel Climate Model (PCM) depicting wind vectors, surface pressure, sea surface temperature, and sea ice concentration. Prepared from data published in the ESG using the FERRET analysis tool by Gary Strand, NCAR. • DOE invests broadly in climate change research • Development of climate models • Climate change simulation • Model intercomparisons • Observational programs • Climate change research is increasingly data intensive • Analysis and intercomparison of simulation and observations from many sources • Data used by model developers, impacts analysts, policymakers 2 Bernholdt_0611

  3. Earth System Grid objectives To support the infrastructural needs of the national and international climate community, ESG is providing crucial technology to securely access, monitor, catalog, transport, and distribute data in today’s Grid computing environment.

  6. Evolving ESG to petascale ESG Data System Evolution 2006 Early 2009 2011 • Central database • Centralized curated data archive • Time aggregation • Distribution by file transport • No ESG responsibility for analysis • Shopping-cart-oriented web portal • Testbed data sharing • Federated metadata • Federated portals • Unified user interface • Selected server-side analysis • Location independence • Distributed aggregation • Manual data sharing • Manual publishing • Full data sharing (add to testbed…) • Synchronized federation • metadata, data • Full suite of server-sideanalysis • Model/observation integration • ESG embedded into desktop productivity tools • GIS integration • Model intercomparison metrics • User support, life cycle maintenance CSSM, IPCC,satellite, In situ biogeochemistry,ecosystems CCSMIPCC ESG Data Archive Terabytes Petabytes
