Archive and AccessArchives preserve data, make them
accessible in meaningful ways , and ensure their information remains available for future generations.
What changes in technology and observing systems are anticipated?
What kinds of data and information should be archived in the future?
What can the Data Centers do to prepare?
Archive ResponsibilitiesAccept information from Data ProducersExercise sufficient control to ensure long-
term preservation and access (stewardship)Ensures the information to be preserved is
independently understandable and accessible now and in the future
Follow policies and procedures that ensure the information is preserved against all reasonable contingencies
IT IssuesPhysical Storage: Paper, Tapes, Spinning Disk
Future: solid state?All ultimately fragile
Security though redundancyMultiple copies, distributed systems
Access : high speed internet, physical media deliveryDistributed systems, multiple access pointsData formats: facilitate access, self describing,
metadata stdsAccess tools that serve data to a variety of audiences
The data can be expected to be well-cared for….but what about the information?
What to archive?NOAA Observing Systems Council
http://www.nosc.noaa.gov/docs/products/NOAA_Procedure_document_final_12-16-1.pdf
Volume of Observations : NCDC stores 3.5 PB todayNPOESS, next-gen NEXRAD : several PB per year
increaseModel outputs : archive them if not easily
reproducibleBut for how long? Shelf life of synthetic data?
Derived products : process raw records to higher levelsExample
Climate Data Records (CDR) Climate Information Records (CIR)
CDR and CIRClimate Data Records (CDRs) are the essential long
term records for climate studies and assessmentsCDRs require updates as our knowledge of the
observing systems and science improvesArchived data must be revisited, reprocessed
Climate Information Records (CIRs) are derived from and directly dependent upon CDRs
Higher level CIRs will be found more useful by a larger number of user communitiesWater managers, energy industry, ecosystem
managersCIRs place more emphasis on access and delivery
Current challengesFully track associations between the archived
information and its users and applicationsProvides an aggregate value of the info for our societyEstablish a 2-way relationship between info and usersProvides a context for the information for future users
Deliver more information to broader communitiesLess reliance on hierarchal systems and more on
networked systems – ideally a blend of the twoFaster transitions from research to operations
Thoughts and questionsThroughout history, significant information
breakthroughs have brought about social and/or technological revolutionsScientific literacy?
The survival of archives across generations has been a political issue, not a technical or physical issue.
Archives must serve society to stay relevant – so what does society want from our archives?
