Lee Laboratory for Atmospheric and Space Physics University of Colorado ================================================================= INTRODUCTION ================================================================= This compact disc contains archival data derived from observations made by the Infrared Interferometer Spectrometer and Radiometer (IRIS) instruments on Voyager 1 and 2 during the Jupiter and Saturn encounters. A separate data set containing observations of Jupiter's Great Red Spot is included. Data contained here were obtained between 1979 and 1981. ================================================================= VOLUME INFORMATION ================================================================= This volume contains maps of atmospheric parameters derived from Voyager 1 and 2 IRIS spectral observations of Jupiter and Saturn. The derived quantities include maps of ammonia and para-hydrogen abundance, atmospheric opacity and temperatures at several pressure levels, and IRIS radiometry. Data were available for North/South mapping sequences at Jupiter and Saturn and high-resolution observations of the Great Red Spot. The incorporated pointing information has been updated with image navigation techniques (C-smithed). Data are separated by spacecraft and target (Jupiter, Saturn, and Red Spot) and are accompanied by PDS label files. This volume follows the structure outlined below: root | |- AAREADME.TXT The file you are reading. | |- ERRATA.TXT Description of known anomalies and | errors present on this volume. | |- VOLDESC.CAT A description of the contents of this | CD_ROM volume in a format readable by | both humans and computers. | |- [CATALOG] A directory containing information | | about the data set. | | | |- CATINFO.TXT Description of files in this directory. | | | |- MISSION.CAT Description of the Voyager missions. | | | |- VG1HOST.CAT Description of the Voyager 1 | |- VG2HOST.CAT and 2 spacecraft. | | | |- VG1INST.CAT Description of the VG1 IRIS instrument. | |- VG2INST.CAT Description of the VG2 IRIS instrument. | | | |- J_NS_DS.CAT Description of the data set(s) and a list of | |- J_RS_DS.CAT pertinent references for each data set. | |- S_NS_DS.CAT | | | |- PERS.CAT A listing of the people involved in the | | production of this data set and CD-ROM. | | | |- REFS.CAT A list of pertinent references. | |- [DATA] A directory containing the data and PDS label | files for the Voyager 1 and 2 Jupiter and | Saturn encounters. | |- VG1_J_NS.DAT Voyager 1 Jupiter North/South map data file. | |- VG2_J_NS.DAT Voyager 2 Jupiter North/South map data file. | |- VG1_J_RS.DAT Voyager 1 Jupiter Great Red Spot map data file. | |- VG2_J_RS.DAT Voyager 2 Jupiter Great Red Spot map data file. | |- VG1_S_NS.DAT Voyager 1 Saturn North/South map data file. | |- VG2_S_NS.DAT Voyager 2 Saturn North/South map data file. | |- VG1_J_NS.LBL PDS label describing VG1_J_NS.DAT. | |- VG2_J_NS.LBL PDS label describing VG2_J_NS.DAT. | |- VG1_J_RS.LBL PDS label describing VG1_J_RS.DAT. | |- VG2_J_RS.LBL PDS label describing VG2_J_RS.DAT. | |- VG1_S_NS.LBL PDS label describing VG1_S_NS.DAT. | |- VG2_S_NS.LBL PDS label describing VG2_S_NS.DAT. ================================================================= DISC FORMAT ================================================================= This disk has been formatted so that a variety of computer systems (e.g. IBM PC, Macintosh, Sun, VAX) may access the data. Specifically, the disk is formatted according to the ISO 9660 level 1 Interchange Standard. For further information, refer to the ISO 9660 Standard Document: RF# ISO 9660-1988, 15 April 1988. ================================================================= FILE FORMAT ================================================================= All data files on this disc are accompanied by detached PDS labels, which describe their contents. PDS TEXT objects include attached labels. All PDS labels include an SFDU label in the first record. Labels have the same file name as the primary data file but have a suffix ".LBL" appended. The data files were extracted from The Planetary Atmospheres Node Data Analysis System (PANDA) at the University of Colorado. Each file is ASCII, with the number of records and record structure documented in the associated PDS labels. ================================================================= ACKNOWLEDGMENTS ================================================================= This archiving project was initiated by Steve Lee of the Planetary Data System (PDS) Atmospheres (ATM) Discipline Node (DN) at the University of Colorado. Assistance in preparing the data set and associated documentation was provided by Sally Lasater and Andrew Weir at the University of Colorado, and Barney Conrath, John Pearl, and Carolyn Martin at Goddard Space Flight Center. The archival products which result from this activity will be delivered to the PDS ATM DN. Assistance in developing the structure of this volume and format of the catalog files was provided principally by Ron Joyner of PDS at JPL. ================================================================= PEER REVIEW ================================================================= The PDS Planetary Atmospheres Node hosted two "Outer Planet Atmospheres" Workshops, in September, 1991 and June 1993. Workshop participants spent several days using these and other data sets in collaborative research activities. The workshops were an integral part of the peer review process for these data sets. The participants in one or both of the workshops were: Chuck Acton (Jet Propulsion Laboratory) Reta Beebe (New Mexico State University) Kirk Benell (LASP, University of Colorado) Nancy Chanover (New Mexico State University) Barney Conrath (Goddard Space Flight Center) Randy Davis (LASP, University of Colorado) Sandy Dueck (Jet Propulsion Laboratory) Mike Flasar (Goddard Space Flight Center) Sue Hess (Jet Propulsion Laboratory) Sally Lasater (LASP, University of Colorado) Steve Lee (LASP, University of Colorado) Julio Magalhaes (Stanford University) Terry Martin (Jet Propulsion Laboratory) Wayne Pryor (LASP, University of Colorado) Pedro Sada (New Mexico State University) Bill Sandel (University of Arizona) Karen Simmons (LASP, University of Colorado) Andrew Weir (LASP, University of Colorado) Bob West (Jet Propulsion Laboratory) ================================================================= DISCLAIMER ================================================================= Although considerable care has gone into making this volume set, errors are both possible and likely. Users of the data are advised to exercise the same caution as they would when dealing with any other unknown data set. Reports of errors or difficulties would be appreciated.
