The process might require that data activities be accompanied by a 3-year proposal which is reviewed by data management peers and by scientists who supply and request data from that activity. A standing oversight committee, akin to those that review academic departments every few years, could advise on longer-term plans and data acquisition 28

Unfortunately, much of the scientific community is not aware of the need to be involved in developing any unified global change data and information management approach. This attitude is part of a pattern: data management has long been considered a secondary aspect of research.

However, because of the extraordinary information requirements that the global change program will make on data management elements, a new mechanism to handle the data will be necessary to augment the existing system. Establish Information Analysis Services Information analysis services for global change research should be established, either at existing data centers or as new information analysis centers (lACs)

Quality assurance and documentation should be at the heart of a data management system supporting the global change program. Only after extensive testing by independent reviewers should important global research datasets be considered accurate.

At a minimum, dataset documentation should contain: • Identification of contributors • Background information • Scope and purpose of the program • Data collection procedures • Station history • Description of instrumentation • Definition of calibrations applied • Full variable definitions • Definition of calculated variables • Description of adjustments • Quality assurance at the center • Modifications made at the center • Limitations of the data • Systematic and random errors • Data transport verification statistics • Full or sample listings • Input/output routines on the transport medium • References

To meet the needs of global change research, a major research effort directed to environmental data management that involves computer scientists, data managers, librarians, archivists, and user scientists is needed over the next decade. Issues to address include the following: • The design of an indexing system tied to the nature of the database.
