  1. The PDS Geosciences Spectral Library is a collection of measurements of Earth, lunar, and meteorite materials to be used to compare to flight measurements. The collection includes the MRO CRISM Spectral Library and contributions from individual investigators. The spectral library may be searched by specimen name, provenance, classification, texture, composition, and other parameters. Data may be plotted online and downloaded via a shopping-cart interface. Questions and comments about the Spectral Library may be posted to the forum Using the Spectral Library.
  2. Release 22 of data from the CRISM, SHARAD, and Radio Science experiments on the Mars Reconnaissance Orbiter is now online at the Geosciences Node. This release covers data acquired between Nov. 9, 2011, and Feb. 8, 2012.
  3. Jun, The label gives you the starting and ending sub-spacecraft points for the entire SHARAD file. Each record in the file has information about a single SHARAD observation, including the sub-spacecraft latitude and longitude at the time of the observation. You'll find these in columns 77, 78, and 79 of each record. See the file RDR.FMT in the LABEL directory of the archive for a description of all the columns. Both the planetocentric and planetographic latitude values are recorded. (For an explanation of the difference, see the PDS Standards Reference, section 2.4, Body-Fixed Planetary Coordinate Systems.) I hope this helps you. Susan Slavney
  4. GRS/HEND data from Release 40 of the Mars Odyssey Mission are now online at the PDS Geosciences Node at http://pds-geosciences.wustl.edu/missions/odyssey/index.htm These raw and derived data were acquired from October 1 through December 31, 2011. There are no GRS/NS (neutron spectrometer) data for this release due to spacecraft orientation.
  5. Data from Release 10 of the Lunar Reconnaissance Orbiter mission are now online. This release includes data acquired between December 15, 2011, and March 14, 2012, for most instruments. It also includes the Mini-RF polar mosaics. Direct links to the LRO archives are on the PDS Geosciences Node LRO web page, and tools for searching, displaying and downloading selected data products are available through the Lunar Orbital Data Explorer.
  6. The current version of CAT is 7.1.1. It's available from our CRISM web page.
  7. Two releases of new data from the PDS Geosciences Node: Release 32 of Mars Exploration Rover data from the APXS, Atmospheric Opacity, Microscopic Imager, Navcam, Pancam, RAT, and Rover Motion Counter experiments is available from the PDS Geosciences Node at http://pds-geosciences.wustl.edu/missions/mer/. This release includes data from the Opportunity rover only, and covers sols 2701 through 2790. Release 21 of Mars Reconnaissance Orbiter data from the CRISM, SHARAD, and Radio Science experiments is available at http://pds-geosciences.wustl.edu/missions/mro/. This release includes data acquired between August 9 and November 8, 2011.
  8. GRS/HEND data from Release 39 of the Mars Odyssey Mission are now online at the PDS Geosciences Node. These raw and derived data were acquired from July 1 through September 30, 2011. There are no GRS/NS (neutron spectrometer) data for this release due to spacecraft orientation.
  9. Data from Release 9 of the Lunar Reconnaissance Orbiter mission are now online. This release includes data acquired between September 15 and December 14, 2011, for most instruments. Direct links to the LRO archives are on the PDS Geosciences Node LRO web page, and tools for searching, displaying and downloading selected data products are available through the Lunar Orbital Data Explorer.
  10. Please send your question directly to the programmer, Sun Yu.
  11. Data are now online from Release 7 of the MESSENGER Mission to Mercury. This release includes data from the first six months of orbital operations, through September 18, 2011. Data from the GRS, NS, MASCS, MLA, XRS, and Radio Science experiments are available from the PDS Geosciences Node MESSENGER web page. The page also has links to the EPPS, MAG, MDIS, and SPICE data sets, which are archived at other PDS nodes.
  12. Rachel, The short answer to your question is no, it doesn't matter if you have trimmed the wavelength range. I asked some CRISM team members and that was the consensus, after going through all their responses. In particular, Frank Morgan says, "There's one other step she might have to take to get the CIRRUS routines to work on TRR3 data. In addition to the spectral subsetting Rachel does, she might also have to remove the two lines at each end of the image. Those are filled with 65535 at all bands in TRR3 data and can cause a "No good data..." failure. With ENVI Basic Tools/Resize Data, click "Spatial Subset" and in the "Lines" boxes, make sure the minimum is >= 3, and the max is <= NL-2 (where NL is the number of lines in the full image, usually something like 420, 480, etc). If Rachel's already doing spatial subsetting and removing the lines at the ends, this won't be a problem." Hope this helps. If you have more questions, post them here; I'll see them. We all apologize for taking so long to respond. Susie
  13. New Mars Reconnaissance Orbiter data from the CRISM, SHARAD, and Radio Science experiments were released by the PDS Geosciences Node on March 1, 2012.

  14. Sarah, The LOLA team has provided additional resources for understanding and using the surface roughness and slope GDRs: 1) Rosenburg, M.A., Aharonson, O., Head, J. W., Kreslavsky, M.A., Mazarico, E., Neumann, G.A., Smith, D.E, Torrence, M.H., Zuber, M.T. (2011), Global Surface Slopes and Roughness of the Moon from the Lunar Orbiter Laser Altimeter, Journal of Geophysical Research, 116, E02001, doi: 10.1029/2010JE003716. (available at http://www.agu.org/pubs/crossref/2011/2010JE003716.shtml ) 2) The LOLA team has included a set of “extra” products that include maps of the coefficients that indicate a measure of surface roughness at http://imbrium.mit.edu/EXTRAS/FRACTAL/.

  24. Well, June came and went without a new CAT release. I have asked the developers on the CRISM team. They expect to release CAT 6.8 by mid-February. It will be used in CRISM Data Users' Workshop being planned for the Lunar and Planetary Science Conference, March 19-23, 2012.
  25. The structure of the SGS record defined in the script is based on the format file summed_gamma_spectra_cols.fmt in the LABEL directory of the SGS archive. By comparing the script and the format file you can figure out how to specify 4-byte real numbers, 8-byte real numbers, 2-byte unsigned integers and character strings in IDL. To modify the script to read AND and AHD files, you'll need to create similar structures based on the AND and AHD format files, in avg_neutron_data_cols.fmt and avg_hend_data_cols.fmt.
