1. CIRS Data Archiving Status Presentation to the Cassini CIRS Team Meudon, France - April 2004 Conor A Nixon (University of Maryland) Mike Flasar (NASA GSFC) The Cassini CIRS Archive Team

2. Archiving Overview Archiving of CIRS data to the PDS (Planetary Data System) is a requirement for Cassini experiments. PDS will make the data publicly available: effectively limits our period for exclusive use & data validation. Archiving to PDS has benefits: CIRS US scientists can then apply to NASA for additional funding to analyze CIRS data.

3. Archiving Requirements Project requirements are: 1. Raw level data (decompressed, edited interferograms) 2. Plus either: a) Calibrated spectra, or b) Calibration software. CIRS approach has been to provide 2(a), plus 2(b) if PDS will accept it on an ‘as is’ basis.

4. Archiving activities since April ‘03 5/8/03 - CIRS Sample Data Volume shipped to reviewers. 5/15/03 - reviewers comments received. May-December 03 - continued work to respond to reviewers comments. 12/3/03 - shipped CIRS Peer Review Volume to reviewers. 1/15/04 - Peer Review Telecon. January-March 04 - continued discussions with PDS node reps to resolve remaining problems. 3/23/04 - Meeting with Lyle Huber and Reta Beebe of PDS to discuss CIRS archiving issues.

5. Peer Review Volume In the last 9-12 months, the principle CIRS archive activity was to re-work the ‘Sample Archive Volume’ of May 03, responding to reviewers criticisms. This resulted in a ‘Peer Review Volume’ which was reviewed by a wider group of persons. Many issues which were thought to have been resolved since the Sample Volume were re-opened, mainly due to conflicting information from PDS on labelling etc.

6. Main Issues Outstanding as of 04/04 PDS labels for variable-length data files.  We now have a new template to use for next time around. What software should be included, especially calibration software.  Vanilla source and executable, yes.  Calibration code: will be included in the ‘extras’ part of the disk. Need to improve documentation.

7. Issues Outstanding (cont.d) Most documentation needs further work; was awaiting resolution of remaining formatting issues. Must include examples of ‘space’ spectra. Need to include NESR data at different spectral resolutions. Miscellaneous: e.g. changes to PDS keywords.

8. Cassini Archiving Delivery Schedule

9. Revised CIRS Archiving Schedule June 2004 - produce second edition of Peer Review Volume. July-August 2004 - resolve any remaining issues with PDS. September 2004 - begin to archive Jupiter Encounter data (10/00-04/01). Dates are subject to circumstances beyond our control, e.g. if PDS changes labelling formats.
