CEOS GRID Task Team

WGISS Task Profile Outline (Task ID: 40)

Title	CEOS GRID Task Team (CG TT)
Output:	1. Establishment of CEOS Grid Technology Core Testbed. 2. Demonstrations of CEOS Grid-enabled Applications.
Task Leader	Lead: Yonsook Enloe, NASA GSFC/SGT. Engineering and Technical Lead: Allan Doyle, NASA GSFC/InternationalInterfaces.
Objectives, Benefits & Rationale	Grid technology provides basic middleware services for seamless and secure distributed computing and data management, making it much easier for CEOS data providers and data users to implement and operate distributed enterprises, especially enterprises involving large amounts of distributed data and requiring user friendly but agency controlled support for access to multiple distributed computer models and computer processing power. The CEOS Grid Task Team (CG TT) has the overall objective of establishing a pervasive CEOS Grid Environment for approved projects, WGISS Test Facilities (WTFs), and demonstrations. This would be accomplished over two years, with the first year project plan approved in fall 2002. The first year focuses on establishing a CEOS Grid Technology Core Testbed among participating agency sites, and demonstrating CEOS Grid-enabled Applications. If this first year is successful in meeting its milestones, then approval will be requested for a second year beginning in October 2003. During the second year, the CEOS Grid testbed and applications will be extended to more CEOS agency sites and made pervasive (i.e., available at every major CEOS agency site and all participating WTFs).
Target End Date	Approved for one year ending September 2003. Proposed for an additional year ending September 2004.
Milestones (major delivery or review dates)	1. March 2003: Establish a CEOS Grid Technology Core with at least three major participating agency nodes. 2. April 2003: Carry out a Midyear Review and Replan to certify progress along the learning curve and to assure realism of the first year plan and success criteria. 3. September 2003: Demonstrate at least three CEOS Grid-enabled Applications, each involving at least one CEOS agency site and one international partner site. 4. September 2004: Infuse applicable Grid technologies into CEOS member agency information systems and into at least one WTF.
Summary Description of Activity	Set up CEOS Grid Technology Core Testbed, demonstrate major CEOS Grid-enabled applications, and infuse Grid technologies and services into main CEOS agency sites and WTFs. This will be carried out in three phases: (1) Prototyping of Grid technologies and services in Technology Core Testbed to obtain lessons learned, (2) implementing Grid-enabled applications to establish proof of concept, and (3) infusing successful Grid technologies and services into major CEOS agency sites and WTFs to establish a pervasive CEOS Grid by the end of the second year.

Participation (agencies involved, names, contacts, and any specific roles)	Core technology testbed sites: USGS EROS Data Center, Sioux Falls NOAA National Climatic Data Center, Asheville ESA Earth Science Research Institute, Frascati NASA Goddard Space Flight Center, Greenbelt Initial Grid-enabled applications: Data Delivery using GridFTP (USGS lead, partners TBD) NOAA Operational Model Archive and Distribution System (NOMADS) (NOAA lead, partners TBD) Data Integration (ESA lead, partners TBD) Advanced Data Grid (ADG), (NASA lead, partners TBD)
Strategy for adoption of results (including specific agency programme plans)	All four major agencies involved in the initial startup year are implementing applications which are supported by major programmes. Once the initial year lessons learned and capabilities have been proved successful, the validated software and services will be infused into the remaining agency sites and selected WTFs.
Outline resource requirements to achieve output (staff time or key needs)	All four initial applications, as well as the engineering and technical staff time and equipment, are supported by existing, funded USGS, NOAA, ESA, and NASA programmes.
