The document discusses the need for a new generation of cyberinfrastructure to support interactive global earth observation. It outlines several prototyping projects that are building examples of systems enabling real-time control of remote instruments, remote data access and analysis. These projects are driving the development of an emerging cyber-architecture using web and grid services to link distributed data repositories and simulations.

"Toward a Global Interactive Earth Observing Cyberinfrastructure" Invited Talk to the 21st International Conference on Interactive Information Processing Systems (IIPS) for Meteorology, Oceanography, and Hydrology Held at the 85th AMS Annual Meeting San Diego, CA January 12, 2005 Dr. Larry Smarr Director, California Institute for Telecommunications and Information Technology Harry E. Gruber Professor, Dept. of Computer Science and Engineering Jacobs School of Engineering, UCSD
- 2. Abstract As the earth sciences move toward an interactive global observation capability, a new generation of cyberinfrastructure is required. Realtime control of remote instruments, remote visualization or large data objects, metadata searching of federated data repositories, and collaborative analysis of complex simulations and observations must be possible using software agents interacting with web and Grid services. Several prototyping projects are underway, funded by NSF, NASA, and NIH, which are building national to global scale examples of such systems. These are driven by remote observation and simulation of the solid earth, oceans, and atmosphere with a specific focus on the coastal zone and environmental hydrology. I will review several of these projects and describe the cyber-architecture which is emerging.
