Mars Express MARSIS: Subsurface Radar Sounding Data with Ionospheric Correction

Subsurface radar sounding data from the Mars Express spacecraft's MARSIS instrument, processed to correct for ionospheric distortion and automated gain control. The dataset is derived from the MARS EXPRESS MARS MARSIS EXPERIMENT DATA RECORD V2.0 Data Set and is provided by the National Aeronautics and Space Administration. It was last updated in March 2026.

Use Cases

• Analyzing subsurface geological layers based on processed radar sounding data.
• Mapping potential subsurface ice or water deposits based on radar return signals.
• Studying Martian ionosphere effects on radar signal propagation based on the described correction process.

Strengths

• Data is processed to correct for ionospheric distortion and automated gain control.
• Derived from the authoritative 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 is unknown, which may limit suitability assessment.
