Utilization of Operational Environmental Satellite Data: Ensuring Readiness for 2010 and Beyond THE NATIONAL ACADEMIES Advisers to the Nation on Science, Engineering, and Medicine 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 government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding 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. Wm. A. Wulf 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 Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council. www.national-academies.org

Utilization of Operational Environmental Satellite Data: Ensuring Readiness for 2010 and Beyond Foreword One of the principal functions of the Space Studies Board and the Aeronautics and Space Engineering Board is to anticipate problems and offer advice on how the relevant federal agencies can position themselves to avoid or mitigate particular issues. This report, Utilization of Operational Environmental Satellite Data: Ensuring Readiness for 2010 and Beyond, is very much in that spirit. The issue addressed by this report is threefold. We are ever more in need of being good stewards of our planetary home. We have as a potential resource the increasing availability of useful and important environmental data, particularly from space. We have an ever-broadening community of users who, armed with the knowledge of our environmental past and present, can effectively apply this knowledge to improve their own lives and advance the public good. The question is how to link the need, the availability of data that can offer solutions, and the users who can apply these data. This report offers useful advice particularly to the National Oceanic and Atmospheric Administration, which has an increasingly important role in acquiring, but also in processing and archiving, environmental data and making it available to the broad and growing community of diverse users. Lennard A. Fisk, Chair Space Studies Board

Utilization of Operational Environmental Satellite Data: Ensuring Readiness for 2010 and Beyond Preface In 2001, following a National Research Council (NRC)-National Oceanic and Atmospheric Administration (NOAA) workshop on opportunities for NOAA’s environmental satellite program, then Space Studies Board Chair John H. McElroy sent a letter to Gregory W. Withee, Assistant Administrator for NOAA’s Satellite and Information Services, outlining three potential studies (see Appendix A). After discussions with NOAA and NASA the Committee on Environmental Satellite Data Utilization was established to address the following tasks (see Appendix B): Review the likely multiplicity of uses of environmental data collected by the nation’s operational environmental satellites, both in terms of the disciplinary applications of the data (e.g., research, operations, meteorology, hydrology, oceanography, rivers, coasts, fisheries, hydrology, agriculture, space weather) and in terms of the institutional or organizational origins of the users (e.g., intra-governmental (at all levels), international, regional, researchers, for-profit, non-profit, and educational entities). Characterize the likely interfaces between NOAA as a data provider and the range of data users, as well as third-party “added-value” commercial and non-profit users who broker applications by converting the data to a more usable form. Assess the implications of these multidirectional interfaces in terms of needs for (a) data accessibility and quality, (b) compatibility and cross-accessibility with data from other government sources, (c) data volume, (d) information technology, (e) user education, and (f) user participation in planning and performance feedback.

Utilization of Operational Environmental Satellite Data: Ensuring Readiness for 2010 and Beyond Identify critical factors that may drive the evolution of data management responsibilities in areas such as real-time processing; data stream transparency, traceability, access, and characterization; data archiving and retrieval; and reprocessing. Recommend appropriate approaches to secure the engagement of the science and applications community in successfully dealing with the challenges identified in the tasks above and in enhancing the utilization of both active short-term and long-term NOAA data archives. This report presents the conclusions and recommendations developed by the committee in response to these tasks. For their help in making its study possible, the committee acknowledges the many individuals who provided briefings and background material.
