2001 Mars Odyssey: GRS CGS

The gamma sensor part of the GRS instrument suite stopped returning data on September 7, 2009. There are no gamma EDR, CGS, or SGS data since that event. See the ERRATA.TXT file for details.  

GRS Corrected Gamma Spectra (CGS) products are organized as a single virtual volume. Each CGS file includes data for a two-hour time span. The products are aggregated in subdirectories by day. The subdirectories are in turn grouped into directories by year.

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