... A more extensive discussion of the specific scientific requirements for data access and data stewardship for a range of applications, 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. The environmental and geospatial data collected by NOAA and its partners, including model output, are an invaluable resource that should be archived and made accessible in a form that allows researchers and educators to conduct analyses and generate products necessary to accurately describe the Earth System.

... Second, it is impossible to anticipate all future applications of a data set, so a data set of uncertain present value may provide the key to some future scientific issue. Third, well calibrated data sets, or at least data sets with well defined error characteristics, are essential to long term climate monitoring and many other Earth System research requirements; this requirement implies a commitment to maintain records of successive improvements, 7 As an illustration, in NOAA's FY2007 budget request, $994 million is requested just for satellite acquisition and satellite observing services, while only $51 million is requested for all of NOAA's Data Centers and information services.

... Metadata are all the information necessary for data to be independently understood by users, to ensure proper stewardship of the data, and to allow for future discovery.8 Metadata are essential for effective archive management throughout the entire data lifecycle, and are the essential data management component that makes an archive useful for data discovery and integration, through data mining and other techniques. Where possible and practical, it is advisable to use established metadata standards.

... Given the widely distributed nature of its data activities and holdings, NOAA could consider its archival process as part of a federation of distributed data sources and archival delivery partners. One particularly promising framework is a decentralized approach to archiving and data provision, enabled by a centralized corporate-level portal that facilitates discovery and access of integrated data sets tailored to user needs.

... 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-upon standards and protocols to ensure that key data sets can be accessed and exchanged. The Committee's final report will discuss in greater depth the factors leading to the decision whether to archive data or not, as well as the potential consequences and tradeoffs of these decisions, in addition to who might be in the best position to make them.

... · Assure that data management systems can support the growth of archived information that occurs during the data lifecycle. During a data lifecycle the archived information may be enhanced by reprocessing, error correction, and with the addition of supplemental data, quality control assessments, and other metadata derived from the scientific research and knowledge building processes.
