MARSIS: Mars Express Subsurface Radar Sounding Data

Subsurface sounding data from the Mars Express MARSIS experiment, processed to correct for Automated Gain Control and ionospheric signal distortion. The dataset is derived from the MARS EXPRESS MARS MARSIS EXPERIMENT DATA RECORD V2.0 Data Set and was last updated in March 2026. It is provided by the National Aeronautics and Space Administration.

Use Cases

• Modeling subsurface geological structures based on processed radar sounding data.
• Investigating potential subsurface ice deposits based on radar signal returns.
• Analyzing ionospheric effects on radar signals for instrument calibration.

Strengths

• Data has been processed to correct for Automated Gain Control and ionospheric signal distortion.
• Derived from the authoritative MARS EXPRESS MARS MARSIS EXPERIMENT DATA RECORD V2.0 Data Set.
• Provided by the National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
