The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal govern- ment on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the char- ter of the National Academy of Sciences, as a parallel organization of outstand- ing engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sci- ences in 1916 to associate the broad community of science and technology with the Academyâs purposes of furthering knowledge and advising the federal govern- ment. Functioning in accordance with general policies determined by the Acad- emy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing ser- vices to the government, the public, and the scientific and engineering communi- ties. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Preface The National Research Council (NRC) impaneled this committee in response to a request from the National Environmental Satellite, Data, and Information Service (NESDIS) of the National Oceanic and Atmospheric Administration (NOAA) to provide high-level advice on how to archive and provide access to the broad range of environmental data NOAA and its partners collect. With finite resources and enormous growth in data volumes, NOAA seeks input on how to identify the observations, model output, and derived products that must be preserved in perpetuity and made readily accessible versus those that require shorter storage life spans or more limited access. The committeeâs full statement of task is included in Appendix A. NOAA is to be commended for addressing its data archiving and access challenges and for seeking external advice for such critical endeav- ors. This final report expands on an interim report in which the com- mittee proposed preliminary principles and guidelines for archiving the environmental data that NOAA currently collects (NRC, 2006). These preliminary ideas, which focused mainly on data archiving, have been refined and expanded to encompass issues of data discovery, access, and integration, as well as data stewardship. Our intent is to provide a foun- dation for NOAA, its partners, and its community of data users to build on as they continue to develop their data archiving and access systems. For example, NOAAâs Data Archiving and Access Requirements (DAAR) Working Group (see Appendix D) will use these principles and guidelines vii
viii PREFACE as they provide ongoing advice to NOAAâs Science Advisory Board on specific data management activities. As part of its deliberations in preparing its interim and final reports, the committee met five times over a 12-month period. At several meet- ings, representatives from across NOAA provided briefings on their data management and archiving activities. A âNOAA Data UsersâData Man- agers Forum,â held in October 2006, brought together individuals from NOAA, other federal agencies, educational institutions, and the private sector to discuss issues of data and product discovery, access, and deliv- ery. This event proved to be exceedingly beneficial to the committee, as were the briefings we received at other meetings regarding NOAAâs Data Management Report (NOAA, 2006a) and the plans of the DAAR Working Group. We also received input describing NOAAâs legal requirements as they relate to data management and archiving; the relative costs of saving certain types of derived data products versus regenerating these products from archived first-stream data; the challenges associated with interagency cooperation on data management issues; and the value to society of archiving and facilitating the discovery, access, and delivery of a broad variety of environmental data. The primary result of the committeeâs effort, and the main focus of this report, is a series of high-level principles that are essential for effective environmental data management. Many of these principles are accompanied by explanatory guidelines intended to help NOAA and its partners apply these principles to their ongoing data management plan- ning. The three main data management functionsâdata stewardship, data archiving, and data accessâare explored in individual chapters. The final chapter describes the essential components and attributes of an inte- grated, enterprise-wide data management system at NOAA. Background and discussion are provided to help readers understand the context, basis, and implications of each principle and guideline, and case studies are used to illustrate key points where appropriate. The committee received input from a large number of individuals as it prepared its interim and final reports. The committee would especially like to thank Tom Karl (Director, National Climatic Data Center), Chris Fox (Director, National Geophysical Data Center), Zdenka Willis (former director, National Oceanographic Data Center), and their administra- tive staffs. Thanks are also offered to the following individuals within NOAA: John Bates, Richard Brooks, Kurt Schnebele, Bonnie Ponwith, Susan McLean, Richard Beeler, Donald Collins, Steve Murawski, Dru Smith, Marc Hodges, Mark Anderes, Maureen Kenny, James OâSullivan, Rick Visbulis, Glenn Rutledge, Steve DelGreco, Neal Lott, Tim Owen, Fred Branski, Robert Bunge, Tim Birdsong, Tony LaVoi, Roy Mendelsson, Keith Dixon, Jaeson Abraham, and Steve Hankin.
