PDS and LRO: Data Archiving Ed Grayzeck Program Manager, PDS Presentation to the PSS 25 Sept, 2006 SWRI, Boulder, CO
What is PDS? • The Planetary Data System’s job is to... • Provide help to NASA missions and other data providers to organize and document their digital planetary data • Collect complete, well-documented planetary data into archives that are peer-reviewed • Make the planetary data available and useful to the science community • Ensure the long-term preservation and usability of the data.
What is PDS? • How PDS makes data available to the public • Data archives reside at the PDS Discipline Nodes where they are maintained by scientists who use the data and who can provide expert help. • Most PDS archives are available online for downloading and some can also be requested on CD or DVD. • PDS provides online search tools to help locate data of interest. PDS Discipline Nodes Atmospheres Node, New Mexico State University in Las Cruces, New Mexico Geosciences Node, Washington University in St. Louis, Missouri PPI(Planetary Plasma Interactions) Node, UCLA, Los Angeles, California Rings Node, SETI Institute, Mountain View, California Small Bodies Node, University of Maryland, College Park, Maryland Imaging Node, U.S. Geologic Survey in Flagstaff, Arizona and Jet Propulsion Laboratory in Pasadena, California PDS Support Nodes NAIF(Navigation and Ancillary Information Facility) Node, Jet Propulsion Laboratory Engineering Node, Jet Propulsion Laboratory
Components of a PDS Archive Types of Data Products: EDRs – Experiment Data Records (raw data) RDRs – Reduced Data Records (derived data) Standard Products – EDRs or RDRs that are generated in pipeline fashion Special Products – RDRs of special interest generated as resources permit • Data products with PDS labels • Index of data products • Calibration data and reports, if any • Documentation • SIS documents • PDS catalog information • Other documentation • Software to read the data, if needed • Optional extra material • Quick-look or browse versions of data • Analysis software
Archiving Steps: Planning • LRO Instrument Team Planning • Designate the team’s archiving point of contact. • Attend Data and Archive Working Group meetings. • Write an Interface Control Document (ICD) to specify work to be done by the Team and by PDS.
Archiving Steps: Planning • Peer Review • A peer review is required for all PDS archives. • The review happens in the design phase while there is still time to make changes if needed. • The review committee is a small number of scientists who are interested in the data. • The PDS Discipline Node leads the review, which is conducted by email and teleconference or in person • LRO Instrument Team Planning, continued... • Design data products and PDS labels. • Write Data Product SIS to describe data products in detail. • Write Archive Volume SIS to describe contents of the complete archive. • Submit sample data products, labels, and draft SISs to a peer review. • All of this is done with help from the team’s designated PDS Node, as needed.
PDS Involvement in LRO • Geosciences as lead node • Advises the LRO Data Working Group (LDWG) lead, Stan Scott • Provided templates and examples for Archive Plan, ICDs, and SISs • Reviewing the draft DMP and relevant ICDs • Assigned to LOLA, LEND, Diviner, and Mini-RF (SAR) instrument teams • Other node activities • PPI is assigned to CRaTER, contact made • Imaging is assigned to LAMP and LROC • Discussions with LROC Data Node commenced • NAIF has begun discussion of SPICE kernel requirements, attends LDWG telecons
Status: DMP and ICDs • DMP • Draft DM&AP from project withStan Scott (LDWG) lead • Due November 2006 • Each instrument team writing its own DM&AP and coordinated in project version for regular deliveries • Draft versions for four of the instrument teams • Team DM&AP are due on Oct 31, 2006 • ICD activities • All drafts are 90% complete • Due Sept 30, 2006 • Signature cycle will start soon • PDS signatories are the Program Manager and relevant Discipline node manager
PDS Future Actions • Geosciences as lead node • Advise on Archive Design and product definition • Complete the draft DMP and relevant ICDs • Work with LOLA, LEND, Diviner, and Mini-RF (SAR) instrument teams to create SISs • Arrange and Interface test(s) for data to PDS including distribution • Other node activities • PPI work with CRaTER on SIS • Imaging continue contact with LAMP and LROC • Complete preps with LROC Data Node • NAIF Concludes ICD with MOC
