    Mars Odyssey, GRS instrument suite

    Hi. I suggest you use the Orbital Data Explorer for Mars, http://ode.rsl.wustl.edu/mars/. Choose the Data Product Search tab, and open the Step One options. Select the desired GRS data sets under the ODY (Odyssey) heading. Then narrow down your search by product ID, location, or other criteria in Step 2. You can preview your search results in Step 3, and finally submit your query in Step 4. You can select the products you wish to download from the search results list. If you already know the ID or file name of the products you want, you can download them directly from the archive by following the links at http://pds-geosciences.wustl.edu/missions/odyssey/grs.html. Don't forget to download the PDS label that accompanies each product (*.LBL). It contains useful metadata about the product.

    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.
