    SHARAD EDR Data Released

    SHARAD EDR data from the ASI team members have been posted, covering previous MRO release 43 and current release 44. With this release, the team has recovered data from deliveries that were missed due to a hiatus in ground operations. The EDR data set is now up to date. See ERRATA.TXT for details. The data are available on the PDS Geosciences Node's SHARAD page.

    Empriical processing in CRISM data analysis

    Dear Sourabh, Only the CRISM TER and MTRDR derived products have been corrected for spectral smile. See these data product descriptions: http://ode.rsl.wustl.edu/mars/pagehelp/quickstartguide/index.html?crism_ter.htm The CRISM Analysis Tool (CAT) does not have code to do this correction. When we analyze CRISM data using CAT, other than for the two products quoted above, we pay attention to the shift in wavelengths as a function of column number. Note that in CAT, the center wavelengths used in spectral plots are those for the middle column only. CAT can be found at the bottom of this page: http://pds-geosciences.wustl.edu/missions/mro/crism.htm The center wavelength and bandpass file information can be found in: http://pds-geosciences.wustl.edu/mro/mro-m-crism-2-edr-v1/mrocr_0001/document/crism_dpsis.pdf.

    Use of uncertainties in gravity model

    Alvaro, I took your question to Frank Lemoine on the MRO gravity team. His reply is below. Susie Slavney From Frank: "The uncertainties that are provided with a gravity model are derived from the diagonal of the covariance matrix of the spherical harmonic solution. They are representation of the coefficient error, but do not account for the correlations between the coefficients in the least squares solution. In order to obtain another realization of the gravity field solution that is perturbed according to the error information in the covariance, it is necessary to create clones, as discussed in this document (developed as part of the work on the GRAIL mission). http://pds-geosciences.wustl.edu/grail/grail-l-lgrs-5-rdr-v1/grail_1001/extras/clones/clone_description.pdf For Mars, the GSFC team has created clones of the GMM-3 gravity model which might be suitable for the user. This model is described in the paper by Antonio Genova et al. (Icarus, 2016). The clones of GMM-3 are available at the following URL. http://pds-geosciences.wustl.edu/mro/mro-m-rss-5-sdp-v1/mrors_1xxx/extras/clones/ The GMM-3 model is available at the following URL. http://pds-geosciences.wustl.edu/mro/mro-m-rss-5-sdp-v1/mrors_1xxx/data/shadr/gmm3_120_sha.tab The descriptive Label for the model is available at this URL. http://pds-geosciences.wustl.edu/mro/mro-m-rss-5-sdp-v1/mrors_1xxx/data/shadr/gmm3_120_sha.lbl If the user wishes to create clones for the JPL gravity model, they can either ask Alex Konopliv at JPL, or download the error covariance (the SHBDR file), and follow the procedure in the above pdf document to manufacture their own gravity field clones. Sincerely, Frank Lemoine NASA Goddard Space Flight Center "

    Mars elevation data: longtitude, lattitude, elevation.

    I asked the ODE developer if she could suggest a way to do this. Here's her answer. She reads this forum too. Hi Susie, Below link shows an example on how to read those MEGDR products with Matlab. The user could modify the code a little bit to output a table with lat, lon, and height. https://www.mathworks.com/matlabcentral/fileexchange/13444-using-data-from-mola?focused=6780621&tab=example&requestedDomain=www.mathworks.com Another way is to convert the PDS IMG to ERDAS IMG in ArcGIS. Then use ERDAS to convert the ERDAS IMG to an ASCII table with lat, lon, and height. Both Matlab and ERDAS are commercial software. Otherwise, the user needs to write his own program to read the PDS IMG data. The label includes everything that the user needs to know to read the data file. Please let me know if the user needs further help. Thanks, June

    Mars elevation data: longtitude, lattitude, elevation.

    The MOLA PEDR Query Tool I mentioned before will allow you to create output as an ASCII text file.

    Odyssey Release 61

    Mars Odyssey Release 61 includes new raw data (EDR) , Derived Neutron Data (DND) and Derived HEND Data (DHD) products covering the period January 1 through March 31, 2017. Averaged Neutron Data (AND) and Averaged HEND Data (AHD) products cover the period December 23, 2016, through March 10, 2017, Ls 240 to 330.

  11. A new data set of MER Spirit Mini-TES artifact-corrected spectra is now available at the PDS Geosciences Node. This data set was prepared by Steve Ruff and funded by the NASA PDART program. See the readme file and the User's Guide for more information.

    Repository for terrestrial geology applied to Mars

    Michael, Please reply to me at geosci@wunder.wustl.edu and tell me more about your project, including the science content and format of data products. Thanks, Susie Slavney
  14. Hi Emily, You don't mention which of the three Mars Climate Sounder (MCS) data sets you are using. If you are looking for surface temperatures, you probably want to use the MCS DDR (Derived Data Record) data set. The primary documentation for this data set is here: https://atmos.nmsu.edu/PDS/data/MROM_2128/DOCUMENT/DP_SIS.PDF. To see if this is the right one, look at Table 2, which describes the columns in the data table. These data tables are ASCII text, so you can open them in any text editor or even in your browser. The columns are also described in a software-readable way in the "format files" in the LABEL directory of the archive, here: https://atmos.nmsu.edu/PDS/data/MROM_2128/LABEL/. The other two MCS data sets are the RDR (Reduced Data Record) and EDR (Experiment Data Record). EDRs are raw data from the instrument sensors. RDRs are calibrated versions of the EDRs. Finally, the DDRs contain data converted to geophysical units, derived from the RDRs. For each of the three data sets, you'll find an overview of its contents in the file CATALOG/DATASET.CAT, a detailed description in the file DOCUMENT/DP_SIS.PDF, and complete column descriptions in *.FMT files in the LABEL directory. All these files are on the MCS archive volumes, which are hosted at the PDS Atmospheres Node at http://pds-atmospheres.nmsu.edu/data_and_services/atmospheres_data/Mars/Mars.html (scroll down to the MRO section). I hope this is enough to get you started. Susie Slavney

    First look in the Orbital Data Explorer's User Manual section on the M3 instrument, here: http://ode.rsl.wustl.edu/moon/pagehelp/quickstartguide/index.html?isros_chandrayaans_m3.htm. At the bottom of the page are some resources for finding and working with M3 data, including the M3 ENVI User's Guide. If you can't find the information you need, please contact the PDS Imaging Node, who archives the M3 data, at https://pds-imaging.jpl.nasa.gov/feedback.html.
