aspects of individual data sets. This could potentially be accomplished through a distributed but federated archival system facilitated via a single user portal.

  • Broad community representation is essential to establish the process whereby data proposed for archiving can be evaluated and prioritized in terms of scientific and societal benefits.

  • Scientific data stewardship should be applied to all archived information so it is preserved, continually accessible, and can be supplemented with additional data as discoveries build understanding and knowledge.

These preliminary principles and guidelines are intended to help NOAA and its partners begin planning specific archiving strategies for the data streams they currently collect as the Committee prepares for the next phase of its work. To effectively implement these ideas, NOAA will need to collaborate closely with its user communities and with other government agencies (e.g., the National Aeronautics and Space Administration (NASA) and the United States Geological Survey (USGS)). NOAA will also need to work with international partners through organizations such as the Group on Earth Observations, Committee on Earth Observation Satellites, International Council for Science, World Meteorological Organization, International Oceanographic Commission, and International Hydrographic Organization to develop internationally agreed standards and protocols to ensure that key data sets can be accessed and exchanged.

During the second phase of its activities, the Committee plans to convene a user forum designed to engage both NOAA data managers and NOAA’s user community in order to gain additional information and insights on effective data access strategies. Following the forum, and after considering additional materials and extensive deliberation, the Committee will release a final report. This document will include an expanded set of principles and guidelines, illustrated with examples, that NOAA and its partners can use to identify the observational and generated data that should be preserved indefinitely versus those that require only limited storage lifetimes or can be readily regenerated from archived first-stream input, and also the extent to which a wide variety should be made available. A more extensive discussion of the specific scientific requirements for data access and data stewardship, including climate change detection and analysis, will also be included, as will further discussion of funding issues, both in general and in the context of specific archiving and access strategies for individual data streams.
