Appendix E provides historical information relevant to this chapter. GUIDING PRINCIPLES The committee believes adherence to the following principles can help ensure the preservation of the climate record from NPP and NPOESS: Accessible and policy-relevant environmental information must be a well-maintained part of our national scientific infrastructure.

For example, many NASA missions pass their data to the National Space Science Data Center at the Goddard Space Flight Center with the expectation that use of the data for long-term studies will be infrequent. The NOAA meteorological satellite data are stored in the National Climatic Data Center (NCDC)

History has shown that review and retrospective reprocessing of data are important elements in understanding climate and the effects of natural and anthropogenic changes on climate trends. Provide additional information, algorithms, and such higher level products as can aid in the future reprocessing of the data.

The National Climatic Data Center and the Long-Term Archive The NOAA National Climatic Data Center is a potential repository of data to support climate research in the coming NPOESS era. NCDC is currently assigned the mission of managing the nation's resource of global climatological in situ and remotely sensed data and information to "promote global environmental stewardships; to describe, monitor and assess the climate; and to support efforts to predict changes in the Earth's environment."8 NCDC receives, processes, controls the quality of, archives, and distributes weather- and climate-related data from a variety of sources, including satellites, ground radar, and in situ measurement systems.

Further, it is anticipated that this load will increase by approximately an order of magnitude by the end of the decade. The scheduled launch in 2005 of the NPOESS Preparatory Project satellite will add another 90 TB of data annually.

These services include rapid access to subsets of the data, sophisticated search tools to locate coincident data, and a focus on providing online search and order fulfillment. These services support the production of customized data products and allow climate researchers to test new algorithms.

Both active archives and long-term archive facilities need to be flexible enough to accommodate changes in the technology they use on timescales between 2 and 5 years. CONCLUDING OBSERVATION Finally, the committee notes that the President's budget for fiscal year 2001 includes some $4 million for activities at NCDC related to development of the LTA.
