Under the banner of EOSDIS Version 0, the EOS Distributed Active Archive Centers (DAACs) are actively engaged in providing a full suite of data and information services to the science community. In March, there were roughly 62,000 accesses to Version 0 (V0) services by 9,700 distinct users, resulting in just over 10,000 requests for data, and‹the true bottom line for Version 0 and the DAACs‹1.96 terabytes of data were provided to users. (Many of the 62,000 accesses were casual WWW accesses.)

V0 is the complete end-to-end ingest, processing, archiving, cataloging, and distribution system used by the DAACs to serve the community. One component of the V0 system is the V0 Information Management System (IMS), which provides the user whose interests cross DAAC or discipline boundaries the V0 capability to obtain, at "one stop," a coherent view of data sets available across the V0 system as a whole, search for data that meet common criteria, e.g., spatial and temporal coverage, and to order whatever combination of data from whatever combination of DAACs that meets his or her needs, without having to know in advance what data sets are available or what their source may be. The V0 IMS, operated now by all of the DAACs, complements DAAC-specific services tailored to the needs of each DAACs individual user community.

Today the V0 IMS features both graphical user interfaces (GUI) and character-based user interfaces (ChUI) acces-sible from each DAAC. Two important improvements to the system will be available in the near future. A World Wide Web (WWW) interface to the V0 IMS has now been demonstrated by the end of June and will be available for use later in the summer. (DAACs now provide some WWW-based services.) Porting of the V0 IMS client software to user workstations (which improves performance by localizing screen generation and thus minimizing network traffic involved in the use of the system) was started in June. Users will soon (no later than September) be able to freely download copies of the client software from an ftp site.

Until the V0 IMS client software becomes available from an ftp site, users may request a copy of the client by contacting any DAAC User Services office or me, Greg Hunolt (E-mail: gregh@ulabsgi.gsfc.nasa.gov, phone 301-286-0653). We will respond on a first-come, first-served basis, gradually at first, but as quickly as we can. I also invite you to bring to my attention any concerns or problems anyone has with any aspect of the overall V0 system (DAACs, local DAAC services, etc., including the V0 system level IMS). I welcome constructive criticism, I guarantee a reply, and I also don't object to hearing about aspects of V0 that users are pleased with!
