The NASA Science User Networks (NSUN) at Ames Research Center, as part of EOSDIS, supports the development of high performance prototype networks to facilitate scientific research requiring high data rate transfers and computationally intensive modeling efforts. As stated in the charter, the primary objective of the NSUN is to design, develop, demonstrate, test, and evaluate prototype networks to facilitate access and use of EOSDIS by the scientific research community.

EOSDIS science working groups have been established to assure that science user requirements are the primary basis for the design, development and operation of EOSDIS. The NSUN working group (NSUNWG) will provide scientific oversight, guidance, and requirements for the development, implementation, and operation of the NSUN. The NSUNWG will provide a focal point for the direct interaction with the scientific research community regarding developments within the NSUN. The topics and issues for which the NSUNWG will be responsible include:

• provide guidance and user feedback on development of NSUN prototype networks
• advise on mechanisms and toolkits to enhance user access to EOSDIS data
• review network requirements and configuration assessment
• advise on network connectivity dedicated to supporting "mission success" user access across all DAAC's
• review activities supporting interoperability among modeling users, including development of collaborative computing capabilities, tools, and shareware.
• access the networks and evaluate performance information

Dr. Joseph Pasquale, UC San Diego, chair
Dr. Leslie Morrissey, NASA ARC, co-chair
Dr. Joyce Penner, Lawrence Livermore National Lab
Dr. Mark Abbott, Oregon State University
Dr. William Emery, University of Colorado
Dr. Christopher Field, Carneggie Institution, Stanford Univ.
Dr. Andrew Rothrock, University of Washington

The NSUNWG has held three meetings to date. The first meeting concerned the charter. The second meeting was focused on a review of the Hughes User Model with special regard for networking elements. The third meeting reviewed network prototyping plans and requirements. The minutes for all meetings are available. A fourth meeting is scheduled for mid-1995.
