2001 Mars Odyssey: GRS AND

Oct. 1, 2024. Release 89 includes new Averaged Neutron Data (AND) acquired between January 13, 2024 and March 28, 2024.

GRS Averaged Neutron Data (AND) products are organized as a single virtual volume. Each data file represents a time period of 15 degrees of solar longitude (Ls). Each record in the file corresponds to a 5x5 degree latitude-longitude bin. Data subdirectories are grouped into directories by mission year.

This online archive is ODY-M-GRS-5-AND-V2.0, the second version of the AND dataset. The data was reprocessed as described in this document. The original version, ODY-M-GRS-5-AND-V1.0, is available upon request.

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