eGY Planning Meeting Boulder, 14-15 February 2005 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 Alternative to No. 3 eGY Planning Meeting Boulder, 14-15 February 2005

eGY Planning Meeting Boulder, 14-15 February 2005 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… 20th Century approach is no longer adequate … finally, do some science Ingest data into a local database… eGY Planning Meeting Boulder, 14-15 February 2005

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 … BACKGROUND The drivers of 21st century science, combined with the technical ability to collect and transmit large amounts of data efficiently (Internet, GRID), have led to new challenges eGY Planning Meeting Boulder, 14-15 February 2005

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

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

VRBO - Architecture Unleashed Data system that meets engineering, operational, and scientific needs for: Near Real Time Data GOES POES User Interface and Displays Nowcast/ Forecast Models Gateway to distributed data CISM End-to-End Models Assimilation of Extreme-Event Data Long Term Archival Data Climatology Models 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 eGY Planning Meeting Boulder, 14-15 February 2005

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

IGY + 50 Planning 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 Alternative to No. 6 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

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

eGY Planning Meeting Boulder, 14-15 February 2005 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

eGY Planning Meeting Boulder, 14-15 February 2005 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
