Withee NESDIS Exec Route: E Building SSMC1 -- Room: 8338 1335 East West Highway Silvery Spring, MD 20910-3284 Dear Greg: It was a pleasure to work with you and your staff during the NRC-NOAA workshop on Opportunities for NOAA's Environmental Satellite Program. Your attendance at essentially the entire workshop was very much appreciated by the participants.

Potential Study: An Unencumbered Vision for the Future All three splinter groups recommended the development of a largely unencum bered vision for the future architecture of NESDIS's satellite and ground systems. In side discussions, several participants quoted the familiar, "Form follows function." NOAA/NESDIS is the de facto and de jure national agent for the conduct of operational Earth observations from space and for the archiving of the resulting data; this places NOAA in an extraordinarily important position in the federal structure.

A study could reexamine the present requirements on the system to assure their continued validity, project potential evolved NPOESS, GOES, and possibly other satellite configurations, and also seek revolutionary architectures going beyond the incremental evolution of the current plans. An examination of the space segment could address satellite size, but also on-board processing, "bent-pipe" data communication, the role of direct broadcast, space cross-links, spacing on orbit, and the scheduled or unscheduled use of excess capacity on launch vehicles such as the Atlas-5 and Delta-4.

Trained, expert personnel moved from one set of spacecraft to the other and provided numerous efficiencies. Corporate reorganiza tions and the merger of the two programs have eliminated this advantage, and the NPOESS effort must stand on its own -- without sharing of development costs and without an easy means to smooth fluctuations in workload as occurred between the separate POES and DMSP activities.

The matrix of possible approaches could include still closer collaborations between NASA and NOAA, increased resources within NOAA for the conduct of instrument and satellite development, and the enlistment of international partners in a wide variety of possible roles. In the last of these, modestly capable international collaborators might, for example, provide small satellites to carry less complex, but important, instruments in support of either research or operational goals.

NOAA will always have a certain core of major users around which its activities tend to revolve, but the agency's expanding roles and missions can bring NOAA into support of varied users of global, coastal, and regional information. A significant part of transitioning research to operations is the entraining of new classes of users through their joint involvement in pilot tests and other collaborations.

In the analysis of conventional data networks, an engineer describes the various linkages using drawings and computers, and examines the capacities and blockages that may occur. It is an appealing picture, and it is tempting to seek to apply this concept to data utilization in NOAA's data world.

In some instances those users may be principally concerned with relative measurements, e.g., a time series showing how a particular phenomenon evolves where the desired information is in the changes rather than their absolute values. In other instances, as in the measurement of climate change, issues of data continuity, calibration, and long-term stability will dominate as researchers examine data over the extended lifetime of an individual sensor or from several sensors on multiple space platforms.

Appendix A 101 cited would certainly be a worthy target, and would require extensive use and re-use of NOAA's environmental data. The workshop participants strongly believe that there is much more of value that can be mined from NOAA's archived and realtime data.
