MESSENGER: GRS Experiment Data Records

The MESSENGER GRS Experiment Data Records (EDRs) consist of uncalibrated science and instrument data collected by the GRS sensor. Each EDR 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 EDRs are stored on PDS volume MESSGRS_1001. Please see below for direct access to the volume.
