MESSENGER: GRS Calibrated Data Records

The MESSENGER GRS Calibrated Data Records (CDRs) consist of calibrated Ge raw spectra, anti-coincidence spectra, shield spectra, shield count rate data, and engineering data. Each CDR is organized as a binary or ASCII table containing observations with a time tag corresponding to a given Earth day, along with a detached ASCII text PDS label file. The files are grouped in directories by Earth year and month.

The GRS CDRs are stored along with the GRS Reduced Data Records (RDRs) and Derived Analysis Products (DAPs) on PDS volume MESSGRS_2001. Please see below for direct access to the volume.  Only directories pertaining to the CDRs are listed below.  Alternatively, to search the archive for data that meet particular criteria, e.g. time and location, use the Mercury Orbital Data Explorer (ODE).
