2001 Mars Odyssey: GRS EDRs

July 1, 2014. Release 48 of Odyssey data covers the period October 1 - December 31, 2013. Delivery of the EDRs for this release has been delayed, but they will be posted soon. Derived data sets DND, DHD, AND, and AHD are available now.

July 11, 2014. The EDRs for Release 48 are now online.

EDRs are Experiment Data Records, also known as "raw" data products. All Gamma Ray Spectrometer  EDR data products are organized online as if they were on one very large "virtual" volume. Data products are aggregated by day, with a separate subdirectory for each day's data. These subdirectories are in turn grouped into directories by year. 

Use the links below for direct HTTP access to any part of the GRS EDR archive. Alternatively, to search the archive for data that meet particular criteria, e.g. time and location, use the Mars Orbital Data Explorer (ODE).
