2001 Mars Odyssey: GRS DND

Jan. 5, 2024. Release 86 includes new Derived Neutron Data (DND) acquired between April 1, 2023 and June 30, 2023.

GRS Derived Neutron Data (DND) products are organized as a single virtual volume. Each DND file includes data for a twenty-four-hour time span. The daily subdirectories are grouped into directories by year.

This online archive is ODY-M-GRS-4-DND-V2.0, the second version of the DND dataset. The data was reprocessed as described in this document. The original version, ODY-M-GRS-4-DND-V1.0, is available upon request.

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