  1. U.S. – China Symposium and Workshop on Climate Variability, September 21-24, 1999, Beijing, China Virtual Collaboratory: How Climate Research can be done Collaboratively using the Internet Nancy N. Soreide, NOAA/PMEL L. Charles Sun, NOAA/NODC Presented by Len Pietrafesa, North Carolina State University

  2. Vision • Societal benefits through climate studies and improved climate prediction • Investing in observations, satellites, models, research • Investments in Information Technology will: • Remove restrictions of the past • Build a pipeline to the future • Maximize the return on investments • Build a Virtual Collaboratory for Climate Research

  3. What is a Collaboratory? The fusion of computers and electronic communications has the potential to dramatically enhance the output and productivity of U. S. researchers. A major step toward realizing that potential can come from combining the interests of the scientific community at large with those of the computer science and engineering community to create integrated, tool-oriented computing and communication systems to support scientific collaboration. Such systems can be called "collaboratories." From "National Collaboratories - Applying Information Technology for Scientific Research," Committee on a National Collaboratory, National Research Council. National Academy Press, Washington, D. C., 1993.

  4. TAO as an example…

  5. TAO set a standard… • Data dissemination in initial project planning • Researcher involvement has assured data quality • Benefits of data dissemination • Wide use of TAO data • Traditional research, modeling, forecasting groups • Over 200 refereed publications in past 5 years • Related disciplines, educational, administrative, public • With recent advances in technology, we can do much more...

  6. What are the elements of a Collaboratory for Climate Research? • Data Access • Centralized, uniform, consistent access to geographically distributed data in a common data format • Data Visualization • Over-plotting data from distributed servers • Interactive plotting with zoom functions, etc. • 3D, Virtual Reality • Collaboration tools • Full collaborative sharing of applications over the Internet

  7. Collaboratory data access • Data Access • Centralized, uniform, consistent access to geographically distributed data in a common data format • Realtime Observing System data • Satellite data • Gridded data / Model outputs • Data & information products • “Data Portal” • A “doorway” to climate data

  8. The Data Portal: a “doorway” to climate data • Why do we need a Data Portal? • Each Project Office provides a highly customized Web sites for their data • but different datasets have different navigation and interface characteristics • so the user faces a bewildering spectrum of data access interfaces and locations • Data Portal is single, uniform, consistent “doorway” to climate data in a common format • User goes to a single location and sees a consistent interface • Complements the customized data access

  9. How do we build a Data Portal? • Build on a proven prototype • Next Generation, NOAAServer 2 prototype software • connects 5 geographically distributed data servers in Silver Spring, Boulder, Seattle • CORBA for network connections • unified interactive Java graphics • data from distributed servers are co-plotted together on the same axis on the users desktop • Atmospheric and oceanic profiles, time series, ADCP data, global gridded data http://www.pmel.noaa.gov/~nns/noaaserver/nodc-coads-tao.html http://www.pmel.noaa.gov/~nns/noaaserver/coads-tao-raster.html http://merlin/dwd/talks/mts98/unified_browse/

  20. Other Technologies for the Collaboratory: • Networks (100 Megabits/sec today, 10 Gigabits/sec in future) • Next Generation Internet (NGI) and Internet 2 • Visualization • Interactive Java graphics • 3D, Virtual reality • Immersion technology • Collaboration tools • high-speed telecommunications systems for advanced collaboration applications • tele-immersion systems allow individuals at different locations to share a single virtual environment • Use networks not airplanes for collaboration

  21. Visualization Tools: 3D Visualization and Virtual Reality (VRML) http://pmel.noaa.gov/visualization http://www.pmel.noaa.gov/vrml

  22. Collaboration Tools: OceanShare • Connects to geographically distributed climate data sets • Uses NOAAServer2 technologies & NCSA’s Habanero • Collaborative features • Interactive Java graphics • Text and line annotations • High-lighting of individual plots • Display of data values on plots • Support for multiple collaborating scientists • Whiteboards • Featured in national HPCC BlueBook 2000 http://www.epic.noaa.gov/collab

Data Portal Data Server One or more Web Servers User Observing System Server CORBA* TAO data support Data Web Browser Java Servlet CORBA* Client Support Network Network Drifter Data support Data Graphics CORBA* Java Application CORBA* Common Object Request Broker Architecture (CORBA) is an industry standard Middleware. CORBA is used in the NOAAServer software from which this effort will leverage. Based on performance indicators, Java Remote Method Invocation (RMI), an alternative middleware, could easily be substituted for CORBA. Data
