  1. The eGY Opportunity Daniel.Baker@lasp.colorado.edu eGY_Team members eGY Planning Meeting Boulder, 14-15 February 2005

  2. Vision of the eGY • Geoscience in this century is given a forward impetus as IGY did 50 years ago Use the geosciences to educate and to alert the public to the excitement of the world around us eGY Planning Meeting Boulder, 14-15 February 2005

  3. 20th Century approach • Search data centers, institutions, observatories, colleagues… • Process data using mostly proprietary codes, run models… • Get data via post, air-mail, e-mail, Web… • … finally, do some science • Ingest data into a local database… eGY Planning Meeting Boulder, 14-15 February 2005

  4. 21st century science drivers Complex System (Earth) science New cross-disciplinary science opportunities Higher resolution – space and time Rapid response Data assimilation into models Challenges: distributed data, cross-disciplinary data, large and complex data sets, open data access and sharing, data discovery, data preservation, data rescue, .. interoperability … eGY Planning Meeting Boulder, 14-15 February 2005

  5. Current Forms of Sharing Geoscience Data • Centralized distribution schemes – World Data Centers (WDC): • Require continuous support for the data acquisition, storage, and distribution • Submission of data remains voluntary • Collected data are often not suitable for submission; e.g., the WDCs only accept absolute geomagnetic measurements “Push Data” Concept eGY Planning Meeting Boulder, 14-15 February 2005

  6. Sharing Distributed Geoscience Data • Publishing and sharing data through World Wide Web: • Avoids additional steps in data preparation for submission to WDC • Achieves greater visibility amongst scientific and user communities • A GRID (“Fabric”) of many interconnected data nodes is a new vision of distributed, self-populating data repositories and centers • World Data Centers become an integral part of the worldwide data “fabric”, serving as “clearing houses” for the permanent data preservation “Pull Data” Concept eGY Planning Meeting Boulder, 14-15 February 2005

  7. Near Real Time Data GOES POES Gateway to distributed data Long Term Archival Data VRBO - Architecture Unleashed Data system that meets engineering, operational, and scientific needs for: • Climatology model for designing satellites • Nowcasts/forecasts that provide situational awareness for satellite operators. • Long term archives of simulated and observed data for testing scientific theory User Interface and Displays Nowcast/ Forecast Models CISM End-to-End Models Assimilation of Extreme-Event Data Climatology Models eGY Planning Meeting Boulder, 14-15 February 2005

  8. International Geophysical Year 1957 - 1958 Allowed scientists to participate in global observations of geoscientific phenomena using common instruments and data processing Gathered data on geoscientific phenomena from around the world Established the World Data Center system …… eGY Planning Meeting Boulder, 14-15 February 2005

  9. IGY + 50Planning for New International Programs International Polar Year 2007 – 2008: IPY is sponsored by ICSU and WMO; expands understanding of the polar regions in the globally-linked environment International Year of Planet Earth: IUGS is leading, sponsored by the UN and UNESCO; will interpret Earth history as a basis for forecasting likely future events International Heliophysical Year 2007: IHY; sponsored by ICSU; will foster international cooperation in the study of heliophysical phenomena now and in the future Electronic Geophysical Year 2007 – 2008: Sponsored by IUGG, endorsed by ICSU; will promote a revolution in geoscientific data availability and access worldwide CAWSES, ILWS, …. eGY Planning Meeting Boulder, 14-15 February 2005

  10. Embrace and extend IGY principles • International cooperation and sharing • Free, universal, open access to data • Timely and convenient access to data • Global, cross-disciplinary scope • Data preservation • Outreach • Capacity building, especially in developing countries eGY Planning Meeting Boulder, 14-15 February 2005

  11. Attractions of eGY • Timely – Virtual Observatory software is becoming available; e-Science initiatives are spreading • Interdisciplinary - data sharing and data accessibility are common issues in all areas of the geosciences • Affordable – low budget needs; technology development is funded elsewhere • Inclusive – opportunities for developed and developing countries • Appealing to young scientists - fast, convenient, comprehensive data access • Complements I*Y initiatives - IPY, IYPE, IHY, and CAWSES • Outreach capability - informs decision makers and public (promotes environmental literacy) • Capacity Building - can be used to reduce the digital divide eGY Planning Meeting Boulder, 14-15 February 2005

  12. Summary • The eGY is an international initiative which envisions data sharing and major deployments of Virtual Geoscience Observatories in cyberspace • eGY has four major themes: • data access • data release • data preservation • science discovery • Capacity building and outreach are primary elements of eGY eGY Planning Meeting Boulder, 14-15 February 2005
