  1. Priyanka,

    Unfortunately the CRISM team has no plans to produce MTRDR products for CRISM observations acquired past May 21, 2012. The current processing that creates the MTRDRs also does VNIR/IR data joining and browse product generation using information from EPF sequences. Once the scanning gimbal started experiencing issues (limited or no EPF sequences), and especially after the IR heaters died (no IR data), using the current processing on those subsequent images became impossible.

  2. The XAS Spectra of Synthesized Glasses bundle has been released. These data have been added to the Spectral Library interface.

    This database includes X-Ray Absorption Near-Edge Structure (XAS) spectral data from a PDART investigation of synthesized glasses (DOI 10.2138/am-2016-5555). In this investigation, multivariate techniques were used to enable accurate XAS measurements of Fe, Cr, Mn, and Ti ratios across the whole spectral region through creation of a broad suite of experimentally homogenized glasses of geological relevance for use as XAS standards. Iron, Cr, Mn, and Ti were analyzed as epoxy-mounted polished glass beads using XAS at the GeoSoilEnviroCARS beamline at the Advanced Photon Source, Argonne National Laboratory using a spot size of ca. 1x1 μm.

  3. The Astromaterials Database bundle is posted.

    This bundle is a compendium of published geochemical data on astromaterials analyzed in terrestrial laboratories. The data were compiled by Kerstin Lehnert and colleagues as part of a PDART project now available online (https://www.astromat.org/) and further archived by the PDS Geosciences Node.

    The data may be accessed here:

  4. Hello. I spoke with members of the CRISM team, and unfortunately there are no plans to produce MTRDR products for CRISM observations acquired during 2020. There will only be 2 or 3 more deliveries from the team, and these deliveries will not include any MTRDR data past May 21, 2012. These deliveries will just fill in the gaps prior to that date.

    Hope this helps,

  5. A new dataset of Venus radar multi-look maps is released at the PDS Geosciences Node.

    Earth-based, polarimetric radar image data for Venus were collected from 1988-2020, using the Arecibo Observatory 12.6-cm (2380 MHz) transmitter in Puerto Rico and receivers at either the Arecibo Observatory or the Green Bank Telescope in West Virginia. This data set contains maps of radar backscatter from Venus assembled from individual looks collected in these observing runs.

    The data were provided by Bruce Campbell of the Smithsonian Institution's Center for Earth and Planetary Studies and archived by the PDS Geosciences Node.
